Swinging activities can include having sex with a partner while being watched; watching others have sex (perhaps with the above mentioned partner); kissing, stroking, or having oral sex with a third or fourth person (called soft swinging); or having penetrative sex with someone other than one's partner (Full Swap), which is the commonly understood definition of swinging.
Scientific research into swinging has been conducted in the USA since the late 1960s.It has consistently found that swingers have better pair-bonds than monogamous couples.However it should be noted that this study may be biased in terms of its sample (i.e.potentially those swinging couples who had stronger relationships would be motivated to complete the questionnaire, or alternatively the stress that swinging may place on a marriage means that only those with higher than average levels of commitment to their partners are able to remain married whilst swinging; additionally, couples that have jealousy or strife issues caused by swinging will not usually stay in the swinging lifestyle).There is a worldwide organization called SDC, (Swingers Date Club) that organises membership exchanges, parties, conventions and group holidays.
However swingers from all over the continent congregate in July and August in the nudist town of Cap d'Agde in the South of France where there are around 8 swinger clubs.In the USA, many off-premise clubs follow a bar or nightclub format, sometimes renting an entire existing bar for scheduled events.This often relegates these activities to suburbia, where bars in large industrial parks which attract a mainstream clientele during weekdays would otherwise sit empty or closed on weekends when offices shut down. There are three standard formats: the bar/nightclub, usually smaller, in city centres and focused around a dance floor; the spa format which has pools, jacuzzis, saunas and steam rooms and where people strip on entry; and the country club format, which is out-of-town, usually serves a free buffet and may include elements of the first two as well as offering large play spaces.History According to Terry Gould's The Lifestyle: A Look at the Erotic Rites of Swingers (ISBN 1552094820), swinging began among U. Air Force pilots and their wives during World War II.Other hard and fast rules at many swing clubs include the use of condoms and changing condoms between partners.Regardless of club rules it is considered polite within the scene to always assume that condoms are to be used.Swingers also meet through lifestyle magazines, personal ads, swinging house parties, and the Internet.
