ENM stands for ethical non-monogamy, which is the practice of being romantically or sexually involved with multiple people who are all aware of and agree to this relationship structure. It is distinguished from infidelity by the knowledge and consent of those involved, and from polygamy by the various relationship structures that can be involved. ENM is an umbrella term for many types of relationship structures, including polyamory, open relationships, and swinging. The specifics of the arrangement can vary, but the key principles of ENM include open dialogue, trust, honesty, and respect for everyones boundaries and feelings. Research has shown that people in ENM relationships experience greater trust, honesty, intimacy, and even friendship toward their partners, as compared to people in other types of relationships. However, it is important to note that cheating can still happen in ENM relationships if the agreed-upon boundaries are not respected.
