Research
Some subjective scientific research into swinging has been conducted in the USA since the late 1960s. The most recent study, based on an Internet questionnaire addressed to visitors of lifestyle-related sites, found swingers are happier in their relationships than the norm.
- 60% of swingers said that swinging improved their relationship and only 1.7% said it made their relationship less happy. Half of those who rated their relationship very happy before becoming swingers maintained it had become even happier.
- 90% of those with less happy relationships said swinging improved them.
- Almost 70% of swingers claimed no problem with controlling jealousy, around a quarter admitted "I have difficulty controlling jealousy when swinging" to be somewhat true but only 6% said this was "Yes, Very Much" true.
- Swingers rate themselves happier (59% against 32% very happy) and their lives much more exciting (76% against 54% exciting) than does the rest of the population, by surprisingly large margins.
There was no difference between the responses of men and women, although more males (70%) than females completed the survey.
This study, while enlightening, is of limited accuracy of the swinging population as a whole, due to its self-selected sampling technique. Internet-based sampling procedures create a substantial potential for bias. It is likely that those swinging couples who had stronger relationships were more motivated to complete the questionnaire. 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. Couples that have jealousy or strife issues caused by swinging will not usually stay in the swinging lifestyle and thus would have been unlikely to respond.
ABC News reporter John Stossel produced an investigative report into the lifestyle. Stossel reported that over 4 million people are swingers, according to estimates by the Kinsey Institute and other researchers. He also cited Terry Gould's research, in which Gould concluded that "couples swing in order to not cheat on their partners." When Stossel asked swinging couples whether they worry that their spouse will "find they like someone else better", one male interviewee replied, "People in the swinging community swing for a reason. They don't swing to go out and find a new wife;" while a woman interviewee asserted, "It makes women more confident -- that they are the ones in charge." Stossel interviewed 12 marriage counselors about the lifestyle. According to Stossel, "not one of them said don't do it", though some also said "getting sexual thrills outside of marriage can threaten a marriage". Nevertheless, the swingers whom Stossel interviewed claimed that "their marriages are stronger because they don't have affairs and they don't lie to each other."
