Swinging, sometimes referred to as the
swinging lifestyle, is "non-monogamous sexual activity, treated much like any other social activity, that can be experienced as a couple."
[1] The phenomenon (or at least its wider discussion and practice) may be seen as part of the
sexual revolution of recent decades, which occurred after the upsurge in sexual activity made possible by the prevalence of
safer sex practices during the same period. Swinging has been called
wife swapping in the past, but this term has been criticized as
androcentric and inaccurately describing the full range of sexual activities in which swingers may take part.
