Polyamory

Polyamory (from Greek πολύ poly, "many, several", and Latin amor, "love") is the practice of, or desire for, intimate relationships involving more than two people, with the knowledge and consent of everyone involved. It has been described as "consensual, ethical, and responsible non-monogamy". The term should not be confused with polysexuality (attraction towards multiple genders or sexes), although the two may overlap in individuals.
