The swing lifestyle is a non-monogamous lifestyle in which sexual activity is deemed to be recreational or social. Swingers may be single or in committed relationships while engaging with other people sexually. This is considered a type of non-monogamy or open relationship. A 2018 study found that 2.35% of Americans identified as swingers and 4.76% had identified as swingers at some point in their lives.
Swinging is believed to have originated during World War II, although documentation of this is slim. Its rise has also been attributed to the Free Love movement of the 1960s.
Swingers can meet and hook up with each other a few different ways, including in private home settings, at swingers' clubs and events, and at swingers' retreats.
Swinging may also be called wife swapping, husband swapping or partner swapping. It may also be spelled "swinglifestyle."
