According to
Terry Gould's
The Lifestyle: A look at the erotic rites of swingers, swinging began among American
Air Force pilots and their wives during
World War II before pilots left for overseas duty. The mortality rate of pilots was so high, as Gould reports, that a close bond arose between pilot families that implied that pilot husbands would care for all the wives as their own – emotionally and sexually – if the husbands were lost. The realities of the demographics and basing of US Army Air Force (USAAF) pilots and crew suggest that this arrangement did not evolve during WWII, instead evolving later. US military personnel in WWII were not accompanied by their families (and many, especially in the USAAF, were single) – the giant military bases where families live while accompanying a deployed soldier, sailor, aviator, or Marine are mostly
Cold War creations. By the time the
Korean War ended, swinging had spread from the military to the
suburbs. This phenomenon was usually referred to as wife-swapping. Later in the 1960s at the height of the
Free Love movement, the activities associated with swinging became more widespread in a variety of social classes and age levels. In the 1970s, sometimes referred to as "The Swinging '70s", swinging activities became more prevalent, but were still considered "alternative" or "fringe" because of their association with non-mainstream groups such as
communes. In 2002, swingers' rights were added to the mission of the [American]
National Coalition for Sexual Freedom. A common myth claims that a "key party" is a form of swinger party, in which male partners place their car or house keys into a common bowl or bag on arriving, and at the end of the evening the female partners randomly select a set of keys from the bowl and are obligated to leave and have sex with its owner. However, numerous researchers have tried unsuccessfully to confirm a first-hand account of such a party, suggesting that they are nothing more than an
urban legend. According to economic studies on swinging, the information and communications technology revolution, together with improvements in medicine, has been effective in reducing some of the costs of swinging and hence in increasing the number of swingers. == Swinger party ==
