Swinging refers to a lifestyle or activity in which individuals and couples engage in sexual activities with others who are also participating in this type of behavior. It often involves group sex, partner swapping, or attending events where people can meet and have sex with multiple partners. The term "swingers" is used to describe those who engage in swinging activity. Swinging is typically practiced by consenting adults who are looking for an alternative form of intimacy outside of traditional monogamous relationships, and it often involves a high level of trust between participants.
