Sexual Penetration - Unlawful Penetration

Unlawful Penetration

Many jurisdictions use the term sexual penetration synonymously with sexual intercourse. Many sex crimes distinguish between penetrative and nonpenetrative sex acts, with penetrative sex acts being regarded more serious than nonpenetrative sexual activities. Laws may specify particular forms of sexual penetration as part of the offense.

"Unlawful sexual penetration in the first degree" is a felony that occurs where the offender "penetrates the vagina, anus or penis of another with any object other than the penis or mouth of the actor", if the victim is "subjected to forcible compulsion", or is "under 12 years of age", or "is incapable of consent by reason of mental defect, mental incapacitation or physical helplessness" —Unlawful sexual penetration in the first degree, Oregon Statutes § 163.411

In the United Kingdom, sexually penetrating a relative is an offence.

Various forms of penetration have at times been considered obscene, and been prohibited. Works containing such penetrations may be considered pornography.
