Hadley appeals his convictions for aggravated sexual abuse in violation of 18 U.S.C. § 2241(a)(1) and abusive sexual contact in violation of 18 U.S.C. § 2244(a)(2). He argues that the district court abused its discretion by improperly admitting evidence of prior acts of sexual abuse and explanatory expert witness testimony. He contends that insufficient evidence exists to convict him on one of the three counts on which he was found guilty. Finally, Hadley challenges his sentence, on the ground that it was not imposed in accordance with the Sentencing Guidelines. The district court exercised jurisdiction pursuant to 18 U.S.C. § 3231. We have jurisdiction over this timely appeal pursuant to 28 U.S.C. § 1291. We affirm.
I
Hadley is a former elementary school teacher who taught for eleven years at the Bureau of Indian Affairs School (BIA school) on the Navajo Indian Reservation at Chilchinbeto, Arizona. Complaints of sexual molestation led to an investigation of Hadley, which resulted in an indictment charging him with eleven counts of sexual abuse involving five minor victims. The district court granted Hadley’s motion to sever, and the subsequent trial dealt only with counts seven through eleven of the superseding indictment. Counts seven through nine charged Hadley with aggravated sexual abuse, attempted aggravated sexual abuse, and abusive sexual contact. These charges arose from allegations that Hadley had committed forcible anal intercourse and other acts of sexual abuse against Roy, a student at the BIA school.
Roy testified at trial to three separate incidents of sexual molestation by Hadley in late 1987 and early 1988. In addition, over Hadley’s objection, the district court allowed other government witnesses to testify that Hadley had forcibly sodomized them when they were minors. The government also presented the expert testimony of Dr. Rosenzweig, a child psychiatrist, who testified on the issue of general behavior characteristics exhibited by victims of child sexual abuse.
The jury found Hadley guilty of the three crimes perpetrated against Roy. Hadley was acquitted on the remaining two counts, which involved less serious allegations by two other students. The district judge sentenced Hadley to 30 years’ imprisonment for his conviction of aggravated sexual abuse as charged in count seven, and to 108 months for the convictions on counts eight and nine. The judge ordered that the sentences for counts eight and nine be served consecutively to the sentence for count seven, and imposed fines totaling $20,000.

Hadley first argues that the district court should not have admitted the prior bad act testimony of witnesses who testified that Hadley had sodomized and sexually abused them when they were children. We review a district court’s decision to admit evidence of prior bad acts under Fed. R.Evid. 404(b) only for an abuse of discretion.
United States v. Brown,
Rule 404(b) allows the introduction of prior bad acts “as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.” Fed.R.Evid. 404(b). We have held that evidence is admissible under Rule 404(b) if: (1) sufficient proof exists for the jury to find that the defendant committed the prior act; (2) the prior act was not too
*851
remote in time; and (3) the prior act is introduced to prove a material issue in the case.
United States v. Ross,
First, we hold that sufficient evidence of the prior bad acts existed for a jury to “reasonably conclude that the act[s] occurred and that the defendant was the actor.”
Huddleston v. United States,
Second, one witness testified to a regular pattern of sodomy and sexual molestation that began when the boy was ten years old, and lasted until 1977 when he was fifteen. Hadley argues that this act is too remote in time to justify admissibility. We have previously declined to adopt an inflexible rule regarding remoteness in the context of Rule 404(b).
See Ross,
Third, Hadley contends that the pri- or bad act evidence was not introduced to prove a material element in the case. Had-ley was charged in count nine with abusive sexual contact. To demonstrate sexual contact, the government had to prove that Hadley acted “with an intent to abuse, humiliate, harass, degrade, or arouse or gratify the sexual desire of any person.” 18 U.S.C. § 2245(3). The district judge found that the prior acts “have to do with alleged activities of Mr. Hadley, of a sexually gratifying nature.” In addition, the evidence helped to demonstrate specific intent, the proof of which was required in all three counts. On this basis, it was properly admitted. Of course, as pointed out above, if the prior acts are used to prove intent, those acts must be similar to the offense charged. The district judge found that they were, and we do not disagree. In all cases, Hadley isolated his student victims and performed acts of sexual gratification upon them, often including anal intercourse. We conclude that this similarity was sufficient to allow the admission of the prior acts as evidence of intent.
Hadley argues that
United States v. Powell,
Hadley urges reliance on a single sentence in Powell: “When a defendant denies participation in the act or acts which constitute the crime, intent is not a material issue for the purpose of applying Rule 404(b).” Id. at 448. At trial, Hadley’s defense was a denial of participation in the acts of which he was convicted; he offered not to argue the issue of intent. Thus, he contends, Powell precludes the government *852 from proving intent with evidence of prior bad acts.
This is not the holding of Powell. Indeed, nothing in Powell on the issue of intent could have been its holding, because the district court’s ruling on the issue was not challenged on appeal. Powell appealed the district court’s decision to admit the prior conviction as relevant to motive. The district court’s ruling on intent was uncontested on appeal. Powell did not challenge the district court’s refusal to admit the evidence on the theory of intent, as this ruling was favorable to him. Significantly, the government did not cross-appeal. Thus, the statement relied on by Hadley was nonbinding dicta which cannot control the outcome in a subsequent case.
Hadley’s argument can be read to suggest we adopt the
Powell
dicta as persuasive authority. The statement, as interpreted by Hadley, goes too far. The government must prove every element of a crime beyond a reasonable doubt.
In re Winship,
We must also investigate, however, whether the prior bad acts should have been excluded because their probative value was substantially outweighed by the danger of unfair prejudice. Fed.R.Evid. 403;
Ross,
Thus, we conclude that the district court did not abuse its discretion in admitting the evidence of Hadley’s prior acts of sexual abuse.

Hadley next contends that the district court improperly admitted the expert testimony of Dr. Rosenzweig, a child psychiatrist who testified for the government. We review the district court’s decision to admit expert psychiatric testimony for abuse of discretion.
United States v. Binder,
Hadley first argues that the expert testimony should have been excluded because it improperly bolstered the testimony of the minor victims. In support of this argument, he cites our decision in Binder, where we held that the district court erroneously admitted expert testimony that addressed the credibility of the abused children. In that ease, however, “the experts testified that [those] particular children in [that] particular case could be believed." Id. at 602 (emphasis added). Dr. Rosenzweig, on the other hand, testified about general behavior characteristics that may be exhibited in children who have been sexually abused, and the testimony was therefore limited “to a discussion of a class of victims generally.” Id. Because this general testimony merely “assisted] the trier of fact in understanding the evi- *853 denee,” id., Dr. Rosenzweig did not improperly bolster the children’s testimony.
Hadley next contends that Dr. Rosenzweig’s testimony failed to qualify under the test adopted in
Frye v. United States,
Finally, Hadley argues that Dr. Rosenzweig’s testimony was more prejudicial than probative, and therefore violated Fed. R.Evid. 403. The testimony helped to explain the testimony of the abused children, and therefore rendered “ ‘appreciable help’ ” to the jury.

We next review Hadley’s contention that there was insufficient evidence to convict him of count eight, attempted aggravated sexual abuse of Roy. In reviewing a claim of insufficient evidence, we must determine whether, viewing the evidence in the light most favorable to the government, “any rational trier of fact could have found the defendant ] guilty beyond a reasonable doubt.”
United States v. Murray,
The facts relating to count eight indicate that in November 1987, Hadley gave Roy a ride home from a swimming pool and persuaded Roy to sit on his lap and drive the vehicle. Upon feeling Hadley’s penis grow erect beneath him, Roy got off his lap and returned to the passenger seat. Only one month earlier, Hadley had used the same modus operandi to penetrate Roy’s anal cavity, which led to his conviction on count seven for aggravated sexual abuse.
We have held that “attempt includes an element of specific intent even if the crime attempted does not.”
United States v. Sneezer,
The government introduced evidence that: (1) Hadley asked Roy to sit on his lap while Hadley was driving; (2) Hadley tried to get Roy to remove his pants; and (3) Roy felt Hadley getting an erection while Roy was sitting on Hadley’s lap. In light of this evidence, together with the similar sexual abuse that occurred a month before, a rational jury could have found beyond a reasonable doubt that Hadley intended to engage in a sexual act with Roy. Furthermore, a rational jury could have concluded that Hadley’s actions constituted sufficient steps “in the course of conduct planned to culminate in the commission of
*854
the crime.”

Finally, Hadley contends that the district court erred by imposing a sentence not in accordance with the Sentencing Guidelines for his conviction on count seven. The district court did not apply the Sentencing Guidelines in imposing a 30-year sentence on that conviction. The court did follow the Sentencing Guidelines when it sentenced Hadley to nine years in prison on counts eight and nine.
Hadley’s contention is without merit. We have held that the Sentencing Guidelines do not apply to conduct that occurred before November 1, 1987.
United States v. Gray,
AFFIRMED.
