Once I had a threesome with my girlfriend and my potencial fiancee boy. I was more concentrated on my girl, as I felt sorry for even a tiny opportunity to make something wrong. Now they are married and live together while I'm abandoned by both of them :D Though before, they both tried to persuade me they had no interest in each other - which was evidently not true when we've spending time together. As for the swinger club, I dream to participate in it once due to the psychological experience, exploring people's nature and possibly more "adequate" self-lurking across my complexes and so on... P.S. You just decided not to sleep with anyone, or there were certain reasons?..
