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 Colorado, public lewdness is typically addressed under the state's indecent exposure laws. According to Colorado Revised Statutes (C.R.S.) 18-7-302, a person commits indecent exposure if they knowingly expose their genitals to the view of any person under circumstances in which such conduct is likely to cause affront or alarm, with the intent to arouse or satisfy the sexual desire of any person. Indecent exposure is generally classified as a class 1 misdemeanor. However, if the individual has two or more prior convictions for indecent exposure or other sexual offenses, the charge can be elevated to a class 6 felony. A conviction for indecent exposure can also require the defendant to register as a sex offender, depending on the circumstances of the case and the individual's criminal history. It's important to note that the specific legal consequences can vary based on the details of the offense and the presence of any aggravating factors.
