A person generally commits the criminal offense of public lewdness or lewd conduct in public if the person knowingly engages in any of the following acts in a public place—or, if not in a public place, the person is reckless about whether another is present who will be offended or alarmed by the person’s (1) act of sexual intercourse; (2) act of deviate sexual intercourse; (3) act of sexual contact with a person’s own private parts or those of another.

Public lewdness laws vary from state to state, and some states define and charge such criminal offenses under indecent exposure laws. Public lewdness is usually a misdemeanor offense, but may be a felony offense under some circumstances. And in some states a conviction for public lewdness may require the defendant to register as a sex offender.

In Wyoming, public lewdness is addressed under the state's indecent exposure laws. According to Wyoming Statutes § 6-4-201, a person is guilty of public indecency if they commit an indecent or obscene act in a public place, or if they are reckless about whether another person present may be offended or alarmed by their actions. This includes acts of sexual intercourse, deviate sexual intercourse, or sexual contact with one's own or another's private parts when done in a public place or in a manner that does not regard the presence of others who may be offended. Public indecency in Wyoming is typically classified as a misdemeanor, but the classification can escalate to a felony under certain circumstances, such as when the offender has previous convictions for similar offenses. The requirement for sex offender registration for a conviction of public lewdness depends on the specific circumstances of the case and the discretion of the court.
