According to Terry Gould's The Lifestyle: A Look at the Erotic Rites of Swingers, swinging began among United States Air Force pilots and their wives during World War II. In this small community, the mortality rate among pilots was significantly high. Gould reports that a close bond between pilots arose, with the implication that the husbands would protect and care for all the wives as their own, both emotionally and sexually, if the husbands were away or lost.
By the time the Korean War ended, the practice of swinging had spread from the military bases to the nearby suburbs. The media promptly dubbed the phenomenon wife-swapping.
The first swingers' organization, the Sexual Freedom League, began in the 1960s in Berkeley, California, in the sexually liberal San Francisco Bay Area. Ultimately, an umbrella organization called the North American Swing Club Association (NASCA) was formed to encourage the dissemination of accurate information about swinging lifestyles across North America.
Eine „akkurate Information“ über Swinging und Gruppensex - allerdings aus meiner Sicht - versuchte ich in der Ausstellung NASS-AH. Rund um die Wände des gesamten Ausstellungskomplexes lief ein Band montierter Fotos des immer gleichen Bildausschnitts.
