Some swingers engage in unprotected sex, a practice known as barebacking, while others follow safe sex practices and will not engage with others who do not also practice safe sex.
Swingers may reduce the risk of STI by exchanging STI test results and serosorting.
Approximately 50% of those who rated their relationship "very happy" before becoming swingers maintained their relationship had become happier.
Some people object to swinging on moral or philosophical grounds.Most religious communities and moralists regard swinging as adultery, not withstanding that it is with the knowledge, consent or encouragement of one spouse to the other.Red rings represent the passion and unbreakable bond between the couple, the yellow background represents the light and fire of desire, the blue color of the vastness of the sky Swinging can take place in a number of contexts, ranging from spontaneous sexual activity involving partner swapping at an informal gathering of friends to planned regular social meetings to "hooking up" with like-minded people at a sex club (also known as a swinger club, not to be confused with a strip club).Different clubs offer varied facilities and atmospheres, and often hold "theme" nights.One 2000 study, based on an Internet questionnaire addressed to visitors of swinger-related sites, found swingers are happier in their relationships than the norm.
60% said that swinging improved their relationship; 1.7% said swinging made their relationship less happy.
The phenomenon of swinging, or at least its wider discussion and practice, is regarded by some as arising from the freer attitudes to sexual activity after the sexual revolution of the 1960s, the invention and availability of the contraceptive pill, and the emergence of treatments for many of the sexually transmitted diseases that were known at that time.
The adoption of safe sex practices became more common in the late 1980s.
According to Stossel, "not one of them said don't do it," though some said "getting sexual thrills outside of marriage can threaten a marriage".
Nevertheless, swingers whom Stossel interviewed claimed "their marriages are stronger because they don't have affairs and they don't lie to each other." 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.
Proponents of swinging argue that safe sex is accepted within the swinging community and the risk of sexual disease is the same for them as for the general population – and that some populations of sexually non-monogamous people have clearly lower rates of STIs than the general population.
