    ________________
    GRUENDER, Circuit Judge.
    A jury found Jason Adam Pumpkin Seed guilty of the sole count of an
    indictment charging him with aggravated sexual abuse and attempted aggravated
    sexual abuse, violations of 18 U.S.C. §§ 2241(a) and 1153. The district court1
    sentenced him to 200 months’ imprisonment. Pumpkin Seed now appeals several
    adverse rulings, including: (1) the denial of his motion to dismiss the indictment; (2)
    the exclusion of evidence under Federal Rule of Evidence 412; and (3) the inclusion
    1
    The Honorable Andrew W. Bogue, now deceased, United States District Judge
    for the District of South Dakota.
    of a jury instruction on attempted aggravated sexual abuse. For the reasons discussed
    below, we affirm.
    I.    BACKGROUND
    On the evening of September 29, 2006, Jason Adam Pumpkin Seed, Heather
    Red Cloud and others met at Red Cloud’s aunt’s home in Wounded Knee, South
    Dakota, for a social gathering. Around 10:00 p.m., Pumpkin Seed and Red Cloud left
    the gathering, though not together. From this point their accounts of the evening’s
    events differ significantly.
    According to Red Cloud, after the two left the gathering, Pumpkin Seed
    grabbed and attacked her behind her aunt’s home. Red Cloud attempted to flee his
    grasp by removing her jacket, but Pumpkin Seed forced her to her knees and
    eventually onto the ground. While on the ground, Pumpkin Seed covered Red
    Cloud’s mouth with his hand, pulled down his pants, forced her jeans down to her
    ankles, and began to have vaginal intercourse with her. During this struggle, Red
    Cloud was eventually able to scream for help and attract the attention of three boys
    who were walking along a nearby bike path. Two of the boys approached and pushed
    Pumpkin Seed off of Red Cloud. Red Cloud, now free, pulled her jeans back up,
    began crying hysterically, hit Pumpkin Seed, and then ran back into her aunt’s home.
    According to Pumpkin Seed, after the two left the gathering, Red Cloud took
    Pumpkin Seed by the arm and they began kissing. Red Cloud took off her jacket and
    the two embraced on the ground, continuing to kiss. Pumpkin Seed unbuttoned his
    pants and her jeans, but he did not engage in any additional sexual advances after Red
    Cloud asked him not to go any further. Instead, the two continued to kiss until Red
    Cloud observed three boys approaching. Red Cloud got nervous and yelled “stop,”
    prompting Pumpkin Seed to stand up. The boys then came over, recognizing Pumpkin
    Seed and Red Cloud, and Pumpkin Seed told them to go away because he was “trying
    -2-
    to get some.” Red Cloud began to curse at Pumpkin Seed, claiming that he had raped
    her. Pumpkin Seed then called Red Cloud a “minor bunner”2 in front of the boys, and
    Red Cloud responded by hitting him and becoming hysterical. Thereafter, Richard
    Little Moon came out of Red Cloud’s aunt’s home, observed the argument, ushered
    Red Cloud into the home, and told Pumpkin Seed to leave.
    Once inside, Red Cloud told her aunt that Pumpkin Seed had raped her. Red
    Cloud’s aunt called the police, and Red Cloud was transported to a hospital. Bethany
    Berry, a nurse midwife, examined Red Cloud and administered a rape kit. Berry
    observed a number of injuries on Red Cloud, including abrasions to her back and left
    knee, a cut lip, and scrapes and scratches on her neck and elbow, but no apparent
    injuries to her vaginal area. Berry also noticed grass stains on Red Cloud’s jeans, dirt
    on the back of her shirt, and grass and debris in her hair. When Berry asked Red
    Cloud whether she had consensual intercourse within the last seventy-two hours, Red
    Cloud answered “no.” Berry then took vaginal and cervical swabs and sent the
    samples to the South Dakota State Forensics Laboratory, which subsequently found
    the presence of semen and foreign pubic hair. The South Dakota laboratory forwarded
    the samples to the FBI, along with DNA samples from Pumpkin Seed, for donor
    identification.
    During the evening of the alleged rape, Bureau of Indian Affairs Special Agent
    Carl Martinez interviewed Red Cloud about the incident. Red Cloud told Martinez
    that Pumpkin Seed had raped her and had ejaculated, either in her or on her. On May
    22, 2007, Martinez presented the results of his investigation into the rape allegations
    to a federal grand jury. He recounted his interview with Red Cloud, including her
    statement that Pumpkin Seed had ejaculated in her or on her, and he discussed the
    South Dakota laboratory’s findings of semen and foreign pubic hair. The grand jury
    2
    At trial, Pumpkin Seed explained that a “minor bunner” is a derogatory term
    for a woman who has a proclivity for engaging in sexual relations with adolescent
    males.
    -3-
    returned a one-count indictment charging Pumpkin Seed with aggravated sexual abuse
    and attempted aggravated sexual abuse. Pumpkin Seed pled not guilty.
    In August 2007, the Government received the FBI laboratory’s results. The FBI
    determined that Pumpkin Seed was not the source of either the semen or foreign pubic
    hair samples from the rape kit and that the two samples did not share a common
    donor. Thereafter, Red Cloud admitted to having consensual sexual relations with
    another man a day and a half before the incident. Red Cloud explained that she had
    lied about her recent sexual history during the rape kit interview to protect the identity
    of her married sexual partner.3 The Government informed Pumpkin Seed’s counsel
    of this information.
    Before trial, Pumpkin Seed filed a motion under Federal Rule of Evidence 412
    to admit evidence of Red Cloud’s sexual history, of past sexual relations between Red
    Cloud and him, of the semen, foreign pubic hair and extragenital injuries discovered
    during Red Cloud’s rape kit procedure, and of Red Cloud’s false answer to the rape-
    kit interview question concerning her recent sexual activity. The district court held
    an in camera hearing on the motion as required by Rule 412(c)(2) and granted the
    motion in part and denied it in part. The district court granted the motion as to any
    evidence of specific past sexual relations between Red Cloud and Pumpkin Seed
    under Rule 412(b)(1)(B), but it denied the motion as to all of the other proffered
    evidence, unless the Government opened the door to any of those subjects at trial.
    Pumpkin Seed also moved to dismiss the indictment, claiming that it was secured by
    Special Agent Martinez’s testimony, which misled the grand jury into believing that
    the semen and pubic hair discovered on the rape kit samples belonged to Pumpkin
    3
    Red Cloud’s admission does not account for the fact that the semen and pubic
    hair samples did not share a common donor (i.e. Red Cloud’s married paramour), and
    nothing in the record resolves this apparent discrepancy. The circumstances
    surrounding this third man are of no moment here, however, because none of Pumpkin
    Seed’s arguments depend on the unknown second donor.
    -4-
    Seed. The district court denied the motion to dismiss the indictment, finding that
    Martinez’s testimony accurately communicated to the grand jury all of the evidence
    then known.
    Before the case was submitted to the jury, Pumpkin Seed objected to the
    submission of a jury instruction defining attempted aggravated sexual abuse.
    Pumpkin Seed argued that the Government’s evidence supported only an instruction
    for the completed offense of aggravated sexual abuse, not an attempt to commit the
    offense. The court overruled the objection. The jury returned a general verdict of
    guilty that did not distinguish between aggravated sexual abuse and attempted
    aggravated sexual abuse.
    II.   DISCUSSION
    A.     Motion to Dismiss the Indictment
    Pumpkin Seed argues that the district court should have granted his motion to
    dismiss the indictment because Special Agent Martinez’s grand jury testimony—that
    Red Cloud told him in an interview that Pumpkin Seed ejaculated in her or on her and
    that the South Dakota laboratory found the presence of semen and foreign pubic hair
    on the rape-kit samples—purposefully deceived the grand jury into believing that
    Pumpkin Seed was the source of the semen and pubic hair. According to Pumpkin
    Seed, this testimony improperly influenced the grand jury’s decision to indict.
    In reviewing the district court’s denial of a motion to dismiss the indictment for
    alleged government misconduct, “we review the district court’s factual findings for
    clear error and its legal conclusions de novo.” United States v. Nieman, 
    520 F.3d 834
    ,
    838 (8th Cir. 2008); see also United States v. Kouba, 
    822 F.2d 768
    , 774 (8th Cir.
    1987) (reviewing for clear error the district court’s denial of a motion to dismiss based
    on alleged prosecutorial misconduct). Here, we find no reversible error in the district
    -5-
    court’s refusal to dismiss the indictment, because “even assuming that there were
    errors in the charging decision that may have followed from the conduct of the
    prosecution, the petit jury’s guilty verdict rendered those errors harmless.” United
    States v. Wilson, 
    565 F.3d 1059
    , 1070 (8th Cir. 2009) (alterations omitted) (quoting
    
    Kouba, 822 F.2d at 774
    ); see United States v. Taken Alive, 
    513 F.3d 899
    , 903-04 (8th
    Cir. 2008) (holding that a petit jury’s guilty verdict renders grand jury error harmless
    because it results in no prejudice to the defendant).4
    B.     Exclusion of Evidence of Red Cloud’s Past Sexual Behavior Under
    Federal Rule of Evidence 412
    Pumpkin Seed also appeals the district court’s exclusion of certain evidence
    under Federal Rule of Evidence 412. First, Pumpkin Seed argues that the district
    court abused its discretion under Rule 412(b)(1)(A) by excluding evidence of specific
    instances of Red Cloud’s sexual behavior, which he offered to prove that one of her
    alleged consensual sexual partners—not Pumpkin Seed—was the source of the
    injuries to her back, knee, lip, neck and elbow. Second, he contends that the district
    court improperly excluded evidence of Red Cloud’s consensual sexual relationship
    with a married man and her false answer to the rape-kit interview question concerning
    her recent sexual activity, which she allegedly gave to conceal that relationship.
    According to Pumpkin Seed, this evidence was admissible under Rule 412(b)(1)(C)
    to prove that Red Cloud had a motive to falsely accuse Pumpkin Seed of rape because
    its exclusion would violate his constitutional rights under the Fifth and Sixth
    Amendments to the United States Constitution.
    4
    Moreover, we agree with the district court’s conclusion that Special Agent
    Martinez’s testimony was not misleading based on the then-available evidence. The
    FBI laboratory results showing that Pumpkin Seed was not the source of the rape-kit
    semen and pubic hair were not available until after the grand jury returned the
    indictment. Special Agent Martinez did not testify that the semen and pubic hair
    belonged to Pumpkin Seed.
    -6-
    Federal Rule of Evidence 412, the federal rape-shield rule, generally prohibits
    the admission of evidence concerning the alleged victim’s past sexual behavior or
    alleged sexual predisposition, subject to certain enumerated exceptions. The rule
    provides, in relevant part:
    (a) Evidence generally inadmissible.—The following evidence is not
    admissible in any civil or criminal proceeding involving alleged sexual
    misconduct except as provided in subdivisions (b) and (c):
    (1) Evidence offered to prove that any alleged victim engaged in
    other sexual behavior.
    (2) Evidence offered to prove any alleged victim’s sexual
    predisposition.
    (b) Exceptions.—
    (1) In a criminal case, the following evidence is admissible, if
    otherwise admissible under these rules:
    (A) evidence of specific instances of sexual behavior by the
    alleged victim offered to prove that a person other than the
    accused was the source of semen, injury or other physical
    evidence;
    . . . and
    (C) evidence the exclusion of which would violate the
    constitutional rights of the defendant.
    “We review a district court’s interpretation and application of the rules of
    evidence de novo and its evidentiary rulings for abuse of discretion.” United States
    v. Street, 
    531 F.3d 703
    , 708 (8th Cir. 2008). However, we review evidentiary rulings
    de novo when they implicate constitutional rights. United States v. White, 
    557 F.3d 855
    , 857 (8th Cir. 2009).
    We turn first to Pumpkin Seed’s argument under Rule 412(b)(1)(A). The
    district court excluded Pumpkin Seed’s evidence of Red Cloud’s past sexual behavior
    -7-
    offered to explain the source of her extragenital injuries. In doing so, the court
    concluded that even if the Government opened the door to the subject at trial by
    eliciting testimony concerning Red Cloud’s injuries, Pumpkin Seed’s proffered
    evidence was not “otherwise admissible” under the Federal Rules of
    Evidence—specifically, under Rule 403—and, therefore, was not subject to the Rule
    412(b)(1)(A) exception. See Fed. R. Evid. 412(b)(1). The district court found that the
    admission of this evidence would violate Rule 403 because “the argument that
    consensual sex with a third person may have caused the injuries to the victim is too
    weak to justify the admission of this highly prejudicial evidence.” See Fed. R. Evid.
    403 (“[Relevant] evidence may be excluded if its probative value is substantially
    outweighed by the danger of unfair prejudice . . . .”).
    In reviewing a district court’s evidentiary ruling under Rule 403, we accord
    “great deference [to] the district court’s balancing of the probative value and
    prejudicial impact of the evidence.” United States v. Ruiz, 
    412 F.3d 871
    , 881 (8th Cir.
    2005). Here, reversal is inappropriate because the record demonstrates that the district
    court engaged in the required balancing process and properly found that admitting
    specific instances of Red Cloud’s consensual sexual behavior to explain her physical
    injuries would violate Rule 403. First, Pumpkin Seed did not make any offer of proof
    concerning the circumstances of Red Cloud’s past sexual activity from which the
    district court could assess the likelihood of her injuries being caused by her
    consensual sexual activity. See United States v. Boyles, 
    57 F.3d 535
    , 548 (7th Cir.
    1995) (finding no error in the district court’s exclusion of evidence of an alleged rape
    victim’s past sexual encounters under Rule 412 where the defendant failed to make
    a proper offer of proof). Absent such an offer of proof, we cannot say that the district
    court abused its discretion in determining that the type and extent of physical injuries
    present on Red Cloud are generally inconsistent with consensual sexual intercourse,
    thereby suggesting that the disputed evidence concerning Red Cloud’s consensual
    relationships has little or no probative value in providing an alternate source for her
    injuries. Cf. Hubbeling v. United States, 
    288 F.3d 363
    , 367 (8th Cir. 2002) (rejecting
    -8-
    defendant’s argument under Rule 412(b)(1)(A) and noting that previous acts of
    consensual sexual intercourse between an adolescent male and the alleged victim did
    not “provide[] an alternate explanation for the extensive injuries discovered during
    [the alleged victim’s] medical examinations”). Second, the probative value of this
    evidence is substantially outweighed by the high risk of unfair prejudice and
    confusion of the issues posed by admitting evidence that Red Cloud was involved in
    at least two sexual encounters with different men, one of whom was married, within
    days of the alleged rape. See United States v. One Feather, 
    702 F.2d 736
    , 739 (8th
    Cir. 1983) (“The policy of Rule 412, to guard against unwarranted intrusion into the
    victim’s private life, may be taken into account in determining the amount of unfair
    prejudice under Rule 403.”); see also United States v. Tail, 
    459 F.3d 854
    , 861 (8th
    Cir. 2006) (“Admission of this evidence [under Rule 412] would have triggered
    mini-trials concerning allegations unrelated to Tail’s case, and thus increased the
    danger of jury confusion and speculation.”); Fed. R. Evid. 412 advisory committee’s
    note (“The rule aims to safeguard the alleged victim against the invasion of privacy,
    potential embarrassment and sexual stereotyping that is associated with public
    disclosure of intimate sexual details and the infusion of sexual innuendo into the
    factfinding process.”). Thus, we conclude that the district court did not abuse its
    discretion by excluding this evidence under Rule 403 and, consequently, Rule
    412(b)(1)(A).5
    5
    Pumpkin Seed has abandoned any argument under Rule 412(b)(1)(A)
    concerning the exclusion of evidence of Red Cloud’s prior sexual behavior based on
    the source of the semen and the foreign pubic hair found on the rape-kit samples by
    failing to argue the issue in his opening brief to this court. See United States v.
    Barnum, 
    564 F.3d 964
    , 968 n.4 (8th Cir. 2009). Such an argument would have been
    unsuccessful in any event. The Government never broached the topic of the semen
    and foreign pubic hair found on the rape-kit samples; thus the proverbial evidentiary
    door remained closed to evidence showing the source of the semen and pubic hair.
    See United States v. White Buffalo, 
    84 F.3d 1052
    , 1054 (8th Cir. 1996).
    -9-
    We turn next to Pumpkin Seed’s argument under Rule 412(b)(1)(C). Pumpkin
    Seed contends that the district court erred by excluding evidence purportedly showing
    that Red Cloud had a motive to falsely accuse him of rape—namely, evidence of Red
    Cloud’s consensual sexual relationship with a married man and her false answer to the
    rape-kit interview question concerning her recent sexual activity. In his supplemental
    briefing in support of his Rule 412 motion before the district court, Pumpkin Seed
    explained that Red Cloud “was protecting the donor of semen in her body because he
    was married, and she suspected that she may have been pregnant by him and it would
    be embarrassing to her and life-destroying to the suspected father.” In his opening
    brief before this court, Pumpkin Seed expanded his theory, postulating that “Red
    Cloud was motivated to make this false accusation to provide herself with an
    explanation if she ended up pregnant or developed a venereal disease from her two
    secret liaisons with the true donors of the semen and pubic hair.” (Emphasis added.)
    Pumpkin Seed argues that the district court should have admitted this evidence under
    Rule 412(b)(1)(C) because its exclusion violates his rights under the Fifth
    Amendment’s Due Process Clause and the Sixth Amendment’s Confrontation Clause.
    In determining the admissibility of a victim’s other sexual behavior under Rule
    412(b)(1)(C), we start with the premise that defendants have a constitutional right
    under the Fifth and Sixth Amendments to introduce evidence in their defense. United
    States v. Bear Stops, 
    997 F.2d 451
    , 454 (8th Cir. 1993); see also United States v.
    Elbert, 
    561 F.3d 771
    , 776 (8th Cir. 2009). The Supreme Court, however, has
    recognized that this constitutional right “is not without limitation.” Michigan v.
    Lucas, 
    500 U.S. 145
    , 149 (1991) (quoting Rock v. Arkansas, 
    483 U.S. 44
    , 55 (1987)).
    “The right may, in appropriate cases, bow to accommodate other legitimate interests
    in the criminal trial process.” 
    Id. Such interests
    include concerns about “harassment,
    prejudice, confusion of the issues, the witness’ safety, or interrogation that is
    repetitive or only marginally relevant.” 
    Id. (quoting Delaware
    v. Van Arsdall, 
    475 U.S. 673
    , 679 (1986)). Such limitations on a defendant’s right to introduce evidence
    are permissible so long as they are not “arbitrary or disproportionate to the purposes
    -10-
    they are designed to serve.” United States v. Bordeaux, 
    400 F.3d 548
    , 558 (8th Cir.
    2005) (quoting 
    Lucas, 500 U.S. at 151
    ). Thus, the key inquiry here is whether the
    district court’s exclusion of evidence concerning Red Cloud’s consensual sexual
    relationship with a married man and her attempt to conceal that relationship by lying
    about her recent sexual activity during the rape-kit interview was arbitrary or
    disproportionate to the purposes that its exclusion was designed to serve. See 
    id. First, we
    conclude that the district court’s exclusion of this evidence was not
    arbitrary. There were numerous purposes for excluding this evidence under Rule 412.
    The exclusion saved Red Cloud from the harassment and embarrassment concomitant
    with discussing the details of one’s past sexual activity, see 
    id., and thwarted
    an
    “unwarranted intrusion into [her] private life—[an effect] that Rule 412 was designed
    to prevent,” see Bear 
    Stops, 997 F.2d at 455
    . The exclusion of this evidence also
    avoided possible confusion of the issues by the jury, see 
    Tail, 459 F.3d at 861
    , and
    prevented a thinly-veiled attack on Red Cloud’s general credibility, see United States
    v. Withorn, 
    204 F.3d 790
    , 795 (8th Cir. 2000) (“[I]mpeaching the victim’s truthfulness
    and showing her capability to fabricate a story ‘are not recognized exceptions to Rule
    412.’” (quoting White 
    Buffalo, 84 F.3d at 1054
    )).6
    Second, we conclude that the district court’s exclusion of this evidence was not
    disproportionate to the purposes served by exclusion. Pumpkin Seed’s only reason
    for seeking to admit this evidence was to demonstrate that Red Cloud had a motive to
    make a false rape allegation. More specifically, Pumpkin Seed argued that she needed
    a cover story to protect her married paramour’s identity in case she became pregnant
    or contracted a sexually-transmitted disease (“STD”) during their relationship. In
    other words, Pumpkin Seed claimed that if Red Cloud became pregnant or got an STD
    as a result of her relationship with the married man, she could blame it on her rape by
    6
    In his supplemental briefing on the Rule 412 motion, Pumpkin Seed argued for
    the admission of Red Cloud’s lie during the rape-kit interview by claiming that “[i]f
    she lies about one fact [X] she is lying about other facts.”
    -11-
    Pumpkin Seed and avoid publicly disclosing her relationship with the married man.
    During the Rule 412 hearing, however, the Government discredited Pumpkin Seed’s
    feared-pregnancy theory. The Government offered that in October 2002, Red Cloud
    underwent a tubal ligation, which made it extremely unlikely that she would fear
    becoming pregnant during the course of her relationship with the married man.
    Accordingly, evidence of Red Cloud’s prior sexual relationship with the married man,
    offered to prove that Red Cloud feared becoming pregnant by him, had little, if any,
    probative value as to Red Cloud’s motive to falsely accuse Pumpkin Seed of rape.
    Pumpkin Seed’s feared-STD theory faces a similar defect.7 An STD, unlike a
    pregnancy, generally is not readily observable by members of the general public, and
    therefore it is highly unlikely that anyone other than her physician or her married
    paramour would know about it. Pumpkin Seed posits no reason why Red Cloud
    would feel the need to make a false rape allegation in order to conceal the identity of
    the source of a feared STD that, by its nature, would not be publicly observable or
    likely to result in public disclosure. See 
    Boyles, 57 F.3d at 548
    . Accordingly,
    evidence of Red Cloud’s prior sexual relationship with the married man, offered to
    prove that Red Cloud feared contracting an STD from him, also lacks probative value
    as to Red Cloud’s motive to falsely accuse Pumpkin Seed of rape. Thus, “[i]n light
    of the minimal probative value of the evidence and the important purpose of the
    exclusion, [the] exclusion of the [evidence] was not disproportionate to the purpose
    behind the exclusion.” See 
    Bordeaux, 400 F.3d at 559
    .
    7
    The admissibility of evidence of Red Cloud’s consensual sexual relationship
    with a married man and of her false answer to a rape-kit question based on Pumpkin
    Seed’s theory that Red Cloud needed a cover story if she got an STD from her married
    paramour is subject to plain error review because Pumpkin Seed raised the STD
    theory for the first time in his opening brief to this court. See 
    Elbert, 561 F.3d at 775
    (“‘When a party has failed to preserve an evidentiary issue for appellate review,’ we
    review for plain error.” (quoting Williams v. Wal-Mart Stores, Inc., 
    922 F.2d 1357
    ,
    1360 (8th Cir. 1990))). However, it makes no difference here whether we subject this
    theory to the stricter plain error standard, because we find no error, plain or otherwise,
    in the court’s exclusion of this evidence.
    -12-
    We also are not persuaded that the Supreme Court’s decision in Olden v.
    Kentucky, 
    488 U.S. 227
    (1988) (per curiam), requires the admission of this evidence
    based on Pumpkin Seed’s pregnancy and STD theories. In Olden, the Court reversed
    Olden’s rape conviction because the Kentucky rape-shield rule improperly denied
    Olden the opportunity to impeach the alleged victim based on bias in violation of the
    Confrontation Clause. 
    Id. at 232.
    Specifically, the Kentucky rape-shield rule
    prevented Olden from introducing evidence of the alleged victim’s sexual behavior
    offered to prove her motive to falsely accuse Olden of rape. 
    Id. at 230.
    Although both
    this case and Olden involve evidence offered to prove that the respective alleged
    victims had a motive to make a false rape allegation, the cases differ in a key
    respect—namely, the evidence’s relative “potential to demonstrate the falsity of [the
    alleged victim’s] testimony.” See 
    id. at 232.
    In Olden, the defendant’s evidence of
    the alleged victim’s extramarital relationship with a married man was highly probative
    of the alleged victim’s motive to make a false rape claim, given that the married man
    caught the alleged victim and Olden in a compromising position, which would
    threaten her ongoing relationship with the married man. 
    Id. Here, instead,
    Pumpkin
    Seed’s theory of Red Cloud’s motive to falsely accuse Pumpkin Seed of rape has little,
    if any, potential to demonstrate the falsity of her testimony. Red Cloud knew that she
    could not get pregnant from her married paramour as a result of her tubal ligation, and
    Pumpkin Seed has made no offer of proof showing that Red Cloud feared contracting
    STDs (which, by their nature, are not readily discoverable by the general public,
    thereby undermining her need for a cover story).8 Accordingly, we conclude that the
    district court did not err in holding that this evidence was inadmissible under Rule
    412(b)(1)(C).

    In his reply brief and at oral argument, Pumpkin Seed for the first time offers
    an Olden-like theory for Red Cloud’s motive to falsely accuse him of rape; that is, that
    Red Cloud feared her relationship with her married paramour would be in jeopardy
    if he discovered that she was having consensual sexual relations with Pumpkin Seed.
    By failing to raise this issue to the district court or to this court in his opening brief,
    however, Pumpkin Seed abandoned this argument. See 
    Barnum, 564 F.3d at 968
    n.4.

    C. Attempted Aggravated Sexual Abuse Instruction
    Pumpkin Seed’s final argument in this appeal is that the district court abused
    its discretion when it overruled his objection to the inclusion of a jury instruction on
    attempted aggravated sexual abuse. Pumpkin Seed alleges that the instruction was
    improper because Red Cloud testified that Pumpkin Seed penetrated her and,
    therefore, the evidence, if believed, only supported a conviction for the completed
    offense of aggravated sexual abuse, not an attempt.
    We review the district court’s choice of jury instructions for an abuse of
    discretion. United States v. No Neck, 
    472 F.3d 1048
    , 1054 (8th Cir. 2007). “We will
    affirm so long as ‘the instructions, taken as a whole, fairly and adequately submitted
    the issues to the jury.’” United States v. Aleman, 
    548 F.3d 1158
    , 1166 (8th Cir. 2008)
    (quoting United States v. Lalley, 
    257 F.3d 751
    , 755 (8th Cir. 2001)), cert. denied, 556
    U.S. ---, 
    77 U.S.L.W. 3656
    (2009).
    Attempted aggravated sexual abuse is a lesser-included offense of aggravated
    sexual abuse. See United States v. Remigio, 
    767 F.2d 730
    , 733 (10th Cir. 1985) (“The
    crime of attempt is a lesser included offense of the substantive crime.”). A district
    court acts within its discretion by giving an instruction on a lesser-included offense
    where:
    (1) a proper request is made; (2) the elements of the lesser offense are
    identical to part of the elements of the greater offense; (3) there is some
    evidence which would justify conviction of a lesser offense; (4) the proof
    on the element or elements differentiating the two crimes is sufficiently
    in dispute so that the jury may consistently find the defendant innocent
    of the greater and guilty of the lesser included offense; and (5) there is
    mutuality, i.e., a charge may be demanded by either the prosecution or
    defense.

    United States v. Herron, 
    539 F.3d 881
    , 885-86 (8th Cir. 2008) (quoting United States
    v. Dodd, 
    483 F.3d 873
    , 876 (8th Cir. 2007)).
    Here, Pumpkin Seed’s arguments on appeal concern the third and fourth Herron
    elements: the existence of evidence justifying a jury conviction of attempted
    aggravated sexual abuse and the existence of a dispute concerning the proof of
    attempted aggravated sexual abuse and (completed) aggravated sexual abuse. Based
    on the Government’s evidence adduced at trial, a jury could have reasonably believed
    either of two scenarios: that Pumpkin Seed penetrated Red Cloud by force with the
    requisite intent, thereby completing the offense of aggravated sexual abuse, or that
    Pumpkin Seed took a substantial step toward completing the offense of aggravated
    sexual abuse by force with the requisite intent without actually penetrating Red Cloud,
    thereby committing an attempt. The jury could have reasonably believed the first
    scenario by accepting Red Cloud’s full account of the incident, including her
    testimony that Pumpkin Seed forced himself onto her and had sexual intercourse with
    her against her will. Alternatively, the jury could have reasonably believed the second
    scenario by accepting part of Red Cloud’s account of the incident, including her
    testimony that Pumpkin Seed forced himself onto her, but accepting part of Pumpkin
    Seed’s account of the incident that there was no vaginal penetration. Accordingly, we
    conclude that the Government presented “some evidence which would justify
    conviction of a lesser offense” and that “the proof on the element or elements
    differentiating the two crimes [was] sufficiently in dispute so that the jury [could
    have] consistently [found Pumpkin Seed] innocent of the greater and guilty of the
    lesser included offense.” See 
    id. at 886.
    Therefore, we conclude that the district court
    did not abuse its discretion in including a jury instruction on the lesser-included
    offense of attempted aggravated sexual abuse.9

    Even if there was insufficient evidence to support the district court’s
    instruction on attempted aggravated sexual abuse, we would still reject Pumpkin
    Seed’s argument. See United States v. Dreamer, 
    88 F.3d 655
    , 658 (8th Cir. 1996)
    (rejecting defendant’s argument that “there was insufficient evidence to support [a

    III.   CONCLUSION
    For the foregoing reasons, we affirm the district court.
    ______________________________
    jury] instruction” by concluding that “[w]hen the district court submits to the jury two
    or more grounds for conviction, for one of which there was insufficient evidence, and
    it is impossible to tell on what grounds the jury decided the defendant’s guilt, we
    cannot reverse the jury’s general verdict of guilty.”). Here, as in Dreamer, we would
    not reverse Pumpkin Seed’s conviction because taken in the light most favorable to
    the guilty verdict, the Government presented sufficient evidence to support Pumpkin
    Seed’s conviction for aggravated sexual abuse, and the jury’s general verdict of guilty
    makes it impossible to determine whether the jury convicted Pumpkin Seed for a
    completed offense or an attempt. See 
    id. -16-
