Swinging, sometimes called wife-swapping, husband-swapping, or partner-swapping, is a sexual activity in which both singles and partners in a committed relationship sexually engage with others for recreational purposes.[1] Swinging is a form of non-monogamy and is an open relationship. People may choose a swinging lifestyle for a variety of reasons. Practitioners cite an increased quality and quantity of sex. Some people may engage in swinging to add variety into their otherwise conventional sex-lives or due to their curiosity. Some couples see swinging as a healthy outlet and means to strengthen their relationship.
