OPINION
SHORT, Judge.After a bench trial, Rachel Janel Oanes was convicted of prostitution in violation of Minn.Stat. § 609.324, subd. 3(1). On appeal, Oanes argues: (1) the evidence is insufficient to support her conviction; (2) the trial court erred by failing to consider the defense of entrapment; and (3) the trial court improperly relied on evidence earlier excluded as irrelevant.
FACTS
On July 6, 1994, an undercover police officer from the Minneapolis Police Department entered “Nite-Lites,” a reputed house of prostitution. Oanes greeted the officer at the door, informing him the cost was $100 and he should pick the woman with whom he would like to spend a “session.” The officer selected Oanes.
Oanes brought the officer to a room with a bed and table. She suggested he remove his clothes, told him he could shower if he wanted, and said she would return shortly. The officer took off his clothes and sat on the bed. Oanes returned after approximately ten minutes and laid down on the bed. After making small talk, Oanes asked the officer to massage her. As he rubbed her shoulders, she raised her back and the straps of her halter top fell over her shoulders. The officer pulled the straps down exposing Oanes’ breasts, and moved his hands over them. When the officer asked if Oanes was going to massage him, she said she could not and told him to finish massaging her front. The officer continued rubbing Oanes’s stomach and then unbuttoned her shorts. When the officer asked for help in removing her clothes, Oanes lifted up her bottom. At the officer’s request, Oanes moved to the middle of the bed and spread her legs apart. After the officer placed his hands on Oanes’s inner thighs and his face close to her vaginal area, the officer stopped and arrested her. Oanes was brought to the police station and another officer returned her to Nite-Lites. While in the car, Oanes informed the second officer that she was the manager of Nite-Lites and had previously been a manager of a sauna in St. Paul.
Prior to trial, Oanes raised the defense of entrapment. Her counsel indicated to the court that she did not wish a preliminary hearing, but would proceed to trial. In his final written argument, Oanes’s counsel again raised and argued the entrapment issue.
At trial, the undercover officer testified his conduct was necessary to “check out” with Oanes and to show he was not a police officer. He testified he refrained from mentioning sex or money when he was with Oanes because, based on prior knowledge, he believed she would leave if he did. When the state attempted to admit Oanes’s statements regarding her management positions, the trial court ruled the information inadmissible because it was not relevant to the current charge of prostitution. In rendering its judgment of conviction, however, the trial court found Oanes
offered that she was the manager of Nite-Lites. She also indicated that she had previously worked at a sauna in St. Paul.
The trial court concluded Oanes intentionally offered, agreed, and engaged in sexual contact for hire. In reaching its decision, the trial court did not address Oanes’s entrapment defense.
ISSUES
I. Was the evidence sufficient to support Oanes’s conviction for prostitution?
II. Did the trial court err by failing to consider Oanes’s defense of entrapment?
III. Did the trial court err by referring, in its verdict, to Oanes’s statements regarding her management of Nite-Lites and a sauna?
*661ANALYSIS
I.
It is a misdemeanor to “engagef ] in prostitution with an individual 18 years of age or above.” Minn.Stat. § 609.324, subd. 3(1) (1994). Prostitution involves “engaging or offering or agreeing to engage for hire in sexual penetration or sexual contact.” Minn.Stat. § 609.321, subd. 9 (1994). “Sexual contact” includes “[t]he intentional touching by an individual of a prostitute’s intimate parts” if it may “reasonably be construed as being for the purpose of satisfying the actor’s sexual impulses.” Id., subd. 10 (1994). In reviewing a claim of insufficiency of the evidence, we must determine whether the evidence, when viewed in a light most favorable to the conviction, reasonably supports the trial court’s conclusion. State v. Webb, 440 N.W.2d 426, 430 (Minn.1989).
A. Sexual Contact
Oanes argues she did not engage in sexual contact because breasts are not “intimate parts” under Minn.Stat. § 609.321, subd. 10. Because the legislature has not defined “intimate parts” in the prostitution statutes, we must construe the words according to common usage. Minn.Stat. § 645.08(1) (1994). A woman’s breasts are commonly considered a sexual and intimate part of her body. See Minn.Stat. §§ 609.341, subd. 5 (1994) (defining “intimate parts” to include a person’s breasts for purposes of the criminal sexual conduct statutes), 617.241, subd. l(b)(iv) (1994) (defining sexual conduct to include physical contact with a female’s breasts), 617.245, subd. 1(e)(4) (1994) (same), 617.246, subd. l(e)(iv) (1994) (same). In the United States, women normally cover their breasts when in public and take offense at a stranger’s touch. See Minn.Stat. §§ 609.343, subd. 1 (making certain sexual contact, which includes the touching of another’s intimate parts as defined in Minn.Stat. § 609.341, subd. 5, criminal), 609.345, subd. 1 (same), 609.3451, subd. 1 (1994) (same).
Our conclusion that a woman’s breast is an intimate body part is supported by precedent of foreign jurisdictions. See, e.g., State v. Taylor, 167 Ariz. 429, 808 P.2d 314, 316 (Ct.App.1990) (noting sexual contact, as defined in the Arizona prostitution statute, includes the fondling of female breasts); State v. Turner, 33 Or.App. 157, 575 P.2d 1007, 1008 (1978) (recognizing, as a matter of law, that breasts are intimate parts under Oregon’s sexual abuse statute), review denied (Or. June 20, 1978); In re Welfare of Adams, 24 Wash.App. 517, 601 P.2d 995, 997 (1979) (relying on Turner and holding that breasts, as a matter of law, are “sexual or other intimate parts” under Washington’s indecent liberties statute).
The legislature enacted the current criminal sexual conduct statutes before the present prostitution sections, and grouped them under the common heading “Sex Crimes,” thus indicating sex crimes, including prostitution, encompass acts of touching another person’s breasts under certain conditions. See Minn.Stat. § 645.16(5) (1994) (allowing consideration of laws on similar subjects when interpreting a statute and discerning the legislature’s intent); see also State v. Dooley, 380 N.W.2d 582, 584 (Minn.App.1986) (finding evidence that the defendant touched the victim’s breast, combined with injury, supported conviction for second-degree criminal sexual conduct), review denied (Minn. Mar. 27,1986).
Other similarities between the sex crimes statutes suggest the validity of using one to interpret the other. Both sections provide essentially the same definition of “sexual penetration” and one major difference between the two crimes, the issue of consent, cannot be used as a defense to a prostitution charge. See Minn.Stat. §§ 609.321, subd. 11 (defining sexual penetration for prostitution offenses), 609.325, subd. 2 (1994) (disallowing the use of the client’s consent as a defense to a prostitution charge); State v. Kelly, 379 N.W.2d 649, 652 (Minn.App.1986) (holding consent of a prostitute’s customer is not a defense to a charge of prostitution); see also Minn.Stat. § 609.341, subd. 12 (1994) (defining sexual penetration for criminal sexual conduct offenses). Thus, the legislature’s failure to specifically define “intimate parts” in section 609.321, does not indicate its desire to deviate from the standard established in *662section 609.341. See Minn.Stat. § 609.321, subd. 3 (1994) (using other sections of chapter 609 to define “force” for purposes of the prostitution statutes); see also Minn.Stat. § 609.3451, subd. 1 (explicitly deviating from the definition of sexual contact (generally, the touching of another’s intimate parts) provided by Minn.Stat. § 609.341, subd. 11(a) (1994)).
B. Satisfaction of Sexual Impulses
Oanes also argues the undercover officer did not have the required intent to sustain conviction because he did not subjectively intend to satisfy his sexual impulses by touching her breasts. However, the statute’s language, “if the acts can reasonably be construed as being for the purpose of satisfying the actor’s sexual impulses,” suggests an objective standard. Minn.Stat. § 609.321, subd. 10 (emphasis added); cf Guinther v. Wilkinson, 679 F.Supp. 1066, 1069-70 (D.Utah 1988) (finding the definition of “sexual activity” in a prostitution statute unconstitutional, in part, because the terms “apparent or actual sexual stimulation or gratification” were wholly capricious and lacking a “standard of objective measurement”) (emphasis added). The statute looks to the intent of the prostitute to determine whether an offer or agreement was made, thus suggesting the client’s subjective intent is not relevant. See State v. Crist, 281 N.W.2d 657, 658 (Minn.1979) (holding the state need prove only that the prostitute “intentionally agreed or offered to engage in sexual intercourse for hire”) (emphasis added). In addition, a prostitution conviction does not require proof beyond a reasonable doubt of the intentions of the client, who is not a defendant. Compare State v. Tibbetts, 281 N.W.2d 499, 500 (Minn.1979) (holding the defendant, charged with criminal sexual conduct, was denied due process by the trial court’s instruction that the jury need only find that his actions could reasonably be construed for the purpose of satisfying his sexual impulses) with 1984 Minn. Laws ch. 525, § 3 (deleting “if the acts can reasonably be construed as being” preceding “for the purpose of satisfying the actor’s sexual or aggressive impulses” in Minn.Stat. § 609.341, subd. 11) (emphasis added).
C. Offer and Agreement
Oanes further argues the record does not establish that she offered to engage for hire in sexual contact or sexual penetration. However, an offer need not be explicit, but may be implied by the defendant’s words and actions. State v. Bennett, 258 N.W.2d 895, 897 (Minn.1977).
When the undercover officer entered Nite-Lites, he was told it would cost $100 for a session with a woman. Although Oanes did not state what a session included, the price suggests inclusion of something more than polite conversation. When the officer accepted the proposition by choosing her, Oanes led him to a room and told him to undress. She later allowed him to remove her clothing and touch her breasts, then asked him to continue massaging her front, and twice spread her legs apart at his suggestion. While Oanes argues her failure to terminate the encounter cannot imply an affirmative offer for sexual conduct, the circumstances indicate she offered to engage in sexual contact or sexual penetration for hire. See State v. Armstrong, 282 Minn. 39, 45, 162 N.W.2d 357, 361-62 (1968) (holding the circumstances, in which a known prostitute was present in an area rife with solicitation of prostitution and entered the car of a stranger without a plausible account of her actions, supported the defendant’s conviction for prostitution); see also City of Yakima v. Emmons, 25 Wash.App. 798, 609 P.2d 973, 976 (1980) (affirming a conviction for prostitution based on the defendant’s offer of a “date” for a fee of $60 and a police officer’s testimony that “date” in street language meant prostitution), review denied (Wash. July 18, 1980). The evidence, when viewed in a light most favorable to conviction, reasonably supports the trial court’s conclusion that Oanes engaged for pay in sexual contact with the officer and offered to engage in sexual penetration or sexual contact for hire.
II.
Oanes argues the trial court erred by failing to provide specific findings and conclusions regarding her asserted defense of en*663trapment. When presiding over a bench trial, a court must, within seven days after completion of the trial, make a general determination of guilt or innocence. Minn. R.Crim.P. 26.01, subd. 2. In a misdemeanor case, the trial court must also make specific, written findings regarding the facts essential to the general finding within seven days after the filing of a notice of appeal. Id. However, after a bench trial, if the trial court omits a factual finding essential to the merits of guilt or innocence, it shall be deemed to have made a finding consistent with the general finding. Id.; see also State v. Scarver, 458 N.W.2d 167, 169 (Minn.App.1990) (remanding for findings regarding the suppression of evidence, an issue separate from the merits of guilt or innocence); State v. Totimeh, 433 N.W.2d 921, 924 (Minn.App.1988) (implying a finding of the intent necessary to prove guilt), review denied (Minn. Feb. 22, 1989); State v. Taylor, 427 N.W.2d 1, 4-5 (Minn.App.1988) (noting the lack of any factual findings and refusing to imply their existence), review denied (Minn. Sept. 28, 1988). But see State v. Grilli 304 Minn. 80, 95, 230 N.W.2d 445, 455 (1975) (stating, in a case decided before the enactment of the Minnesota Rules of Criminal Procedure, that if a trial court is to act as finder of fact solely on the issue of entrapment, it must expressly decide the issue and provide findings of fact).
This case involves a misdemeanor offense. Therefore, the trial court had no obligation to make any specific findings of fact until seven days after Oanes filed her notice of appeal. Minn.R.Crim.P. 26.01, subd. 2. The purpose behind rule 26.01, subdivision 2, is to conserve judicial resources and not to require a written statement of specific findings in cases involving relatively minor infractions unless a defendant makes the unlikely choice to take an appeal. It would be impractical to require trial judges to track the procedural postures of all eases and to file findings seven days after the filing of a notice of appeal in the absence of any prompting by the appellant. Thus, an appealing misdemeanant must expressly advise the trial judge of the need to provide a full set of written factual findings. Cf. Frank v. Illinois Farmers Ins. Co., 336 N.W.2d 307, 311 (Minn.1983) (noting, in a civil case, parties have the burden of bringing omitted issues to the attention of the trial court and holding the failure to do so by a motion for amended findings forfeits the right to appellate review of those issues); Anderson v. Peterson’s N. Branch Mill, Inc., 503 N.W.2d 517, 518-19 (Minn.App.1993) (same); Pacific Mut. Door Co. v. James, 465 N.W.2d 696, 701 (Minn.App.1991) (same); Love v. Amsler, 441 N.W.2d 555, 560 (Minn.App.1989) (same), review denied (Minn. Aug. 15, 1989). Because Oanes offers no evidence suggesting that she informed the trial court of the need for a complete statement of factual findings to support the determination of guilt, it was not error for the trial court to provide an incomplete justification for its decision regarding criminal liability.
Even if the trial court had an obligation sua sponte to provide Oanes with a complete justification of its decision, its omission of the issue of entrapment is not fatal, but requires us to imply a finding that is consistent with the trial court’s determination of guilt.1 See Minn.R.Crim.P. 26.01, subd. 2 (providing that, if the trial court omits a finding on any issue of fact essential to sustain the determination of guilt or innocence, “it shall be deemed to have made a finding consistent with the general finding”) (emphasis added); State v. Olson, 478 N.W.2d 218, 220 (Minn.App.1991) (stating that, in acquitting the defendant, the trial court made an implied finding regarding the strength of his alibi defense); Totimeh, 433 N.W.2d at 924 (implying a finding of the intent necessary to prove guilt); see also Minn.R.Crim.P. 26.01 cmt. (“The consequences of an omission of a finding on an essential fact comes from Minn.R.Civ.P. 49[.01](a).”); Regents of Univ. of Minn. v. Medical Inc., 382 N.W.2d 201, 210 (Minn.App.1986) (holding that, as a consequence of the trial court’s omission of findings regard*664ing the affirmative defense of patent misuse in a civil case, the court of appeals “must imply findings consistent with the verdict”), review denied (Minn. Apr. 18, 1986), cert. denied, 479 U.S. 910, 107 S.Ct. 307, 93 L.Ed.2d 282 (1986). Compare Minn.R.Civ.P. 52.01 1985 advisory comm, note (explaining factual findings exist to permit meaningful appellate review) with Crowley Co. v. Metropolitan Airports Comm’n, 394 N.W.2d 542, 545 (Minn.App.1986) (recognizing that appellate courts may exercise their function in the absence of findings, provided that the record is reasonably clear and the facts are not seriously disputed and quoting Roberson v. Roberson, 296 Minn. 476, 478, 206 N.W.2d 347, 348 (1973), as authority). Under these circumstances, Oanes’s argument is actually whether the evidence is sufficient to sustain a rejection of her asserted defense. See Totimeh, 433 N.W.2d at 924 (addressing the question of omitted findings in a discussion of the evidence’s sufficiency to support the conclusions).
A defendant must raise an entrapment defense by establishing by a fair preponderance of the evidence that a government actor initiated the criminal idea. State v. Ford, 276 N.W.2d 178, 182 (Minn.1979). Although the officer first approached Nite-Lites, the evidence shows Oanes was predisposed to exchange sex for money on his arrival. Oanes immediately informed the officer, without any inquiry on his part, of the cost for a session with a woman of his choice. When the officer indicated his agreement, Oanes led him to a room and suggested he undress. While the officer may have initially approached Oanes, he merely accepted her offer when he arrived at the house. See Grilli, 304 Minn, at 89, 91-92, 230 N.W.2d at 452 (holding predisposition may be shown by evidence of the defendant’s active solicitation of the crime); State v. Olson, 361 N.W.2d 899, 905 (Minn.App.1985) (noting the defendant must establish the state actor did more than merely solicit the crime), rev’d in part on other grounds, 379 N.W.2d 524 (Minn.1986). Furthermore, although the officer undressed Oanes, she assisted him and complied with his later requests concerning her position, indicating in no way that she was not predisposed to do what his actions suggested. The officer made his requests once and did not have to further entice compliance. Under these circumstances, in which Oanes failed to establish by a fair preponderance of the evidence that she was not predisposed to commit an act of prostitution, she failed to raise an entrapment defense. Cf. Crist, 281 N.W.2d at 658 (affirming the trial court’s determination that no entrapment existed because the evidence supported the conclusion that the defendant initiated the criminal activity and was predisposed to commit prostitution). Thus, the facts regarding Oanes’s failure to raise this issue were not essential to sustain her conviction for prostitution. The trial court did not err in failing to make findings of fact addressing Oanes’s alleged entrapment.
III.
A trial court should not consider legally irrelevant facts. Juster Bros. v. Christgau, 214 Minn. 108, 120, 7 N.W.2d 501, 508 (1943) (quoting Morgan v. United States, 298 U.S. 468, 480, 56 S.Ct. 906, 911, 80 L.Ed. 1288 (1936)). Oanes argues the trial court committed reversible error because it included a reference to Oanes’s statements that were ruled irrelevant to the prostitution charge. However, even if the court erroneously admitted and considered this evidence, the error does not require reversal unless it substantially affected Oanes’s rights. See Minn.R.Evid. 103(a) (error may not be predicated on a ruling admitting evidence unless a substantial right of the party is affected); Uselman v. Uselman, 464 N.W.2d 130, 138 (Minn.1990) (providing for a new trial based on an erroneous evidentiary ruling only when the appellant can demonstrate prejudicial error); State v. Orfi, 511 N.W.2d 464, 470 (Minn.App.1994) (denying a request for remand because the improper admission of testimony was harmless beyond a reasonable doubt), review denied (Minn. Mar. 15, 1994).
The trial court briefly mentioned, amidst 33 other findings of fact, Oanes’s statements regarding her management positions at Nite-Lites and a sauna in St. Paul. The trial court’s conclusions of law dealt solely with the events on the evening of July 6. Those events sufficiently supported Oanes’s convic*665tion for prostitution without resort to her statements regarding her prior and current employment status. See State v. Morgan, 296 N.W.2d 397, 404 (Minn.1980) (finding no prejudice when the allegedly improper evidence was unrelated to the charged offense); State v. Hjerstrom, 287 N.W.2d 625, 628 (Minn.1979) (upholding a conviction, despite the trial court’s error, because the evidence overwhelmingly established the defendant’s guilt). Under these circumstances, we hold the trial court’s consideration of the statements was harmless beyond a reasonable doubt.
DECISION
The evidence supports Oanes’s conviction for prostitution based on her engagement for hire in sexual contact and her offer to engage for hire in sexual contact or sexual intercourse. In addition, any error by the trial court in failing to consider her entrapment defense and in referring to statements unrelated to the offense was not prejudicial.
Affirmed.
. We agree that, in gross misdemeanor and felony cases, rule 26.01, subdivision 2 requires trial courts to make such findings sua sponte. However, the rule expressly mandates our response to this misdemeanor situation.
