Yes I have. It's almost always the same guy every time I am single...he's gorgeous and we are super sexually compaitable and when we are both between relationships, we hook up. It's meaningless. He's like that guy you have that agreement with that if you are both alone and someday the stars line up right when you are super old you will be together if no one else ever comes along. We aren't good relationship wise (we have been down that very SHORT road haha). We want different things, we are on different life plans, we could never live together, and it's almost a miracle we are friends. We are best buddies when we are single, we don't talk unless we need really honest advice if we are in relationships. But it always worked for us because we were always on the same page. Sex was our equalizer, and it worked out fantastically, and all it meant was that neither of us had to have a bad day and come home and feel alone.
