Swinging or partner swapping (sometimes referred to as the swinging lifestyle or simply the lifestyle) is a non-monogamous behavior, in which both partners in a committed relationship agree, as a couple, for both partners to engage in sexual activities with other couples as a recreational or social activity. Swinging can take place in a number of contexts, ranging from a spontaneous sexual activity at an informal social gathering of friends to a swingers' club and can involve internet-based introduction services.
