Wife swapping and dating
Some argue that strict monogamy is the ideal form for marital relationships and that sexual relations should only take place between marriage partners or, perhaps, between partners in a committed monogamous relationship.
Swingers are exposed to the same types of risks as people who engage in casual sex, with the main concerns being the risk of pregnancy and of contracting a sexually transmitted infection (STI).
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.
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.
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.
Many cite an increased quality, quantity, and frequency of sex.
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.
