Sexual penetration

Sexual penetration is the penetration of a bodily orifice, such as the vagina, anus or mouth, with a body part or another object, as part of a sexual activity.

When a penis penetrates a woman's vagina, it is called vaginal or sexual intercourse; when a penis penetrates another's anus, it is called anal intercourse. Penetration of the mouth by a penis is called fellatio. If one or more fingers are used to penetrate an orifice, it is called digital penetration. Penetration of an orifice with an object, such as a dildo, vibrator or other sex toy may also be referred to as sexual penetration, but not usually referred to as sexual intercourse. The use of a tongue for penetration is called oral sex.
