Open relationships
Extracted from the Wikipedia article Open relationship.
Open relationships include any type of romantic relationship (dating, marriage, etc.) that is open. An "open" relationship means one or more parties have permission to be romantically or sexually involved with people outside of the relationship. This is opposed to the traditionally "closed" relationship, where both parties agree on being with one another exclusively. The concept of an open relationship has been recognized since the 1970s.
