The sex is awesome
I just started a polyamorous relationship with a married couple. She really prefers sex with women and so does he so......the idea of a strong friendship rather than just bed-hopping really appealed to me but I was pleasantly surprised at how great the sex is as well. But it's not everything; we are very well-rounded, fit and educated people with many interests so there is always something to do / talk about. And so far jealousy has not been a problem; they are very strongly committed and loving. I feel lucky to be part of this.
