I'm in a long term relationship with a man, we opened it up years ago and he's had a couple of girlfriends since, I've had a girlfriend and now I have a second long term relationship with a man. It all works fine, what the first man and I have together can never be replaced. Only completed by other relationships. But not everybody can do this, it seems some people really get hurt so you have to be careful. Honesty and respect on all parts has been really important to us.
