Closed swinging is a type of swinging that involves sexual activities that occur behind closed doors with an individual other than one's primary partner.
More About Closed Swinging
Closed swinging allows for a different level of freedom for swinging individuals. The sexual activity can occur at the same time as the other swinging couple, or not, but it is always in a room separate from the primary partners. This type of swinging requires a degree of trust between couples, and added arousal might result from the thought of one's partner being with another and not knowing what occurred between them, which contrasts open swinging.
