"Polyamory is the practice of, or desire for, intimate relationships with more than one partner, with the informed consent of all partners involved. It has been described as "consensual, ethical, and responsible non-monogamy". People who identify as polyamorous may believe in an open relationship with a conscious management of jealousy and reject the view that sexual and relational exclusivity are necessary for deep, committed, long-term loving relationships. Others prefer to restrict their sexual activity to only members of the group, a closed polyamorous relationship which is usually referred to as polyfidelity."
