Sexual intercourse, also known as copulation or coitus, commonly refers to the insertion of a male's penis into a female's vagina for the purposes of sexual pleasure or reproduction. The term may also describe other sexual penetrative acts, such as anal sex, oral sex and fingering, or use of a strap-on dildo, which can be practiced by heterosexual and homosexual pairings or more than two partners.

Sexual intercourse can play a strong role in human bonding, often being used solely for pleasure and leading to stronger emotional bonds.Non-penetrative sex (for example, non-penetrative cunnilingus) has been referred to as "outercourse", but may also be among the sexual acts contributing to human bonding and considered intercourse. The term sex can be taken to mean any mutual genital stimulation or to mean any form of sexual activity (i.e. all forms of intercourse and "outercourse"). Individuals can be at risk of contracting sexually transmitted diseases, and thus safe sex practices are advised.
