I just realized I have never provided my input to this thread. I am straight but definitely have bi-tendencies. My BFF, who introduced me to thongs when we were maybe 19, is the only guy I've ever done anything with but we've never had sex. I've never thought that masturbating with another guy implied one was gay but perhaps bi since we are now both married and have families. We also have a lot of affection for one another and if there was ever a guy I was 'in love with', it would undoubtedly be him. When I first found out that my BFF wore thongs (that's detailed in my first thong story) I automatically assumed that he was gay/bi, but not out because we were in the military. This was 1990 and we were both still in our teens and I'm sure I didn't have a full grasp on exactly what to think at the time. Anyways, the fact that he wore thongs, to me, seemed like an indicator of his sexual proclivity, and kind of opened my mind to accepting that about myself. Fast forward nearly 30 years...he's my BFF for a lot of different reasons including underwear, and our mutual love and affection for one another.
