I am in a poly relationship which some people would call an open relationship, but I don't consider it the same thing. Swinging/open relationships are more about the sex, poly is more about the love. My fiance and I are expecting our first child and our girlfriend is totally on board (she already has 3 kids). We have an open and loving relationship with communication and respect being the most important things to the three of us. I just view myself as someone who is wired a little bit differently, I find it easy to love multiple people and it enriches my life.
