In human sexual behavior, promiscuity denotes sex with relatively many partners. Polygamy is distinguished from promiscuity in that the former refers to numerous romantic relationships, whether sexual or not, while the latter refers simply to sexual activity, without there necessarily being any further connection between the individuals involved.
Promiscuity is common in many animal species. Some species have promiscuous mating systems, ranging from polyandry and polygyny to mating systems with no stable relationships where mating between two individuals is a one-time event. Many species form stable pair bonds but still mate with other individuals outside the pair. In biology, incidents of promiscuity in species that form pair bonds are usually called extra-pair copulations.
