Polyamory

Four to five percent of all adults are in open or polyamorous relationships. 17 % of adults 18 to forty four have had sex with some one else with the consent of their partner. 28% of adults say it's not natural for humans to be in a monogamous relationship. 29%) of adults under 30 consider polyamory to be morally acceptable, compared to six%. So that's what polyamory is and that's how surprisingly common it is.
