Outercourse is sexual activity that does not involve penetration such as sexual intercourse, anal sex or oral sex. No bodily fluids are intended to be exchanged, and outercourse is therefore often considered a practice of safer sex as well as of birth control (but see below for exceptions).
Other specific forms of outercourse include:
- axillary intercourse: putting the penis in the other person's armpit
- interfemoral intercourse: putting the penis between the other person's thighs
- mammary intercourse ("tit sex"): putting the penis between the other person's breasts
- "Frot" (short for frottage) or "phrot" (alternate spelling) among homosexual men tends to imply genital to genital rubbing. Advocates of this practice represent it as a safer and more erotic alternative to anal sex.
- The female equivalent is sometimes refered to as tribadism.
Outercourse in preparation of intercourse is also called foreplay.
