There are few people who flourish in a relationship where each partner is encouraged to have separate intimate adventures. Two people that share this special designation trust their partner will return, and they are usually correct. The partners are able to separate physical intimacy from their lives. They are able to share without jealousy, and many of them review their adventures. This is rare in a society where people are taught to find one special person and have an exclusive relationship.

Society tends to frown on these types of relationships, and few couples admit they have them. It takes effort, but many find other people who share the same viewpoint. Some partners restrict their adventures to people they know, and this is known as swinging. There are people who prefer to experience new people outside of their circle. They believe this keeps their relationship exciting as well as healthy for both of them.
