Promiscuity Definition from Encyclopedia Dictionaries & Glossaries
Promiscuity, in human sexual behaviour, is the practice of having casual sex frequently with different partners or of being indiscriminate in the choice of sexual partners, as in prostitution. The term can carry a moral judgement and is viewed in the context of a mainstream social ideal for sexual activity to occur within exclusive committed relationships. A common example of behavior viewed as promiscuous within the mainstream social ideals of many cultures is a one-night stand.
