Sexual penetration
Sexual penetration is the insertion of a body part or other object into a body orifice, such as the mouth, vagina or anus, as part of human sexual activity or sexual behavior in non-human animals.
The term is most commonly used in statute law in the context of proscribing certain sexual activities. Terms such as "sexual intercourse" or "carnal knowledge" are more commonly found in older statutes, while many modern criminal statutes use the term "sexual penetration" because it is a broad term encompassing (unless otherwise qualified) any form of penetrative sexual activity, including digital (i.e., the fingers) or with an object, and may involve only the most minimal penetration. Some jurisdictions refer to some forms of penetration as "acts of indecency", or other terminology.
Definitions[edit]
When a penis is inserted into a vagina, it is generally called vaginal sex, vaginal intercourse,[1][2] or penis-in-vagina (PIV) sex.[3] When a penis penetrates another person's anus, it is called anal sex or anal intercourse.[4][5] Penetrative oral sex may involve penetration of the mouth by a penis (fellatio) or the use of the tongue to penetrate a vagina or vulva (cunnilingus). The tongue may also penetrate the anus during anilingus. If one or more fingers are used to penetrate an orifice, it is called fingering or digital penetration. The insertion of an object, such as a dildo, vibrator or other sex toy, into a person's genital area or anus may also be considered sexual penetration.
