Swinging, sometimes called wife swapping, husband swapping or partner swapping, is a non-monogamous behavior in which both singles and partners in a committed relationship engage in sexual activities with others as a recreational or social activity. Swinging is a form of open relationship. Some couples see swinging as a healthy outlet and means to strengthen their relationship. The swinger community sometimes refers to itself as 'the lifestyle', or as 'the alternative lifestyle'. Another term, 'hotwife / hotwifing' specifically refers to a married woman who often has sexual relations with different men, with the approval of her husband.
