Sexual intercourse or copulation is the union of the sex organs of two sexually reproducing animals. The two entities may be of opposite sexes, or they may be hermaphroditic, as is the case with snails. This is sometimes called just sex, while the term is also colloquially used at times to include oral sex and anal sex.

For most non-human animals, sexual intercourse is used only for reproduction, through insemination and subsequent internal fertilization. However, bonobos, dolphins, and chimpanzees are known to engage in sexual intercourse even when the female is not in estrus, the most fertile period of time in the female's reproductive cycle. In most instances, humans have sex primarily for pleasure. This behavior in the above mentioned animals is also presumed to be for pleasure, which in turn strengthens social bonds.
