The term which describes a partner’s other partners or lovers. In a polyamorous relationship, a partner will simultaneously be a metamour and have multiple metamours. Typically a metamour is the person, in an open network, with whom you will not share a direct sexual/loving relationship.
Unlike mistresses and cheating, metamour is used when the relationship is completely transparent and open; there are no secrets.
