Watching another couple during sexual relations. May also include foreplay with other partners, sometimes including oral sex but no vaginal penetration. Can add spice to a casual relationship & allow them to have fun without the risk of disease or jealousy. Many couples start out as soft swingers as they first explore swinging. But don't think that soft swingers will always convert to full swapping.
Partners swap, but have sex in separate threesome chat rooms. Closed swinging allows for a more intimate experience. Some people feel it allows them more freedom to explore & fewer interruptions of their enjoyment.
Partners swap & have sex in the same room, or bed. This includes orgies & is great for exhibitionists & voyeurs, who can show off or just enjoy watching their partner play. Some people find 3 way dating or open swinging allows for total release of the sexual desires & fantasies. In order for open swinging to be successful, none of the members of the group can be jealous.
