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).
Some practices of outercourse include sexual roleplaying, heavy petting, clothed frotteurism, and mutual masturbation.
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.
Note that interfemoral intercourse and genital rubbing, although notionally forms of outercourse, can carry a risk of pregnancy
through transfer of sperm-bearing fluids such as semen
or Cowper's fluid
to the sex organs, and that any of the activities above can pose a risk of sexually transmitted diseases
if any body fluids are deposited on wounds or mucous membranes such as those of the sex organs or anal membranes.
Outercourse in preparation of intercourse is also called foreplay.
