Wife swapping and dating
Research on swinging has been conducted in the United States since the late 1960s.
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.
Swinging, sometimes called wife swapping, husband swapping or partner swapping, is sexual activity in which both singles and partners in a committed relationship engage in such activities with others as a recreational or social activity.
Swinging is a form of non-monogamy and is an open relationship.
Some couples see swinging as a healthy outlet and means to strengthen their relationship.
Stossel's report in 2005 cited Terry Gould's research, which concluded that "couples swing in order to not cheat on their partners".
When Stossel asked swinging couples whether they worry their spouse will "find they like someone else better," one male replied, "People in the swinging community swing for a reason.
Swinging is also known to take place in semi-public venues such as hotels, resorts, or cruise ships, or often in private homes.
In 2018, a study of the prevalence of nonmonogamous practices in the United States estimated that 2.35% of Americans currently self-identify as swingers and 4.76% had identified as swingers at some point in their lifetime.
