My opinion is that if you try anything once, you as straight as you were before. If you keep going back for more, your definitely bi. If you predominantly like guys and fuck them a lot more frequently, your getting close to being Gay.

Of course, it depends too on what you want to be. If you want to call your self straight, bi, or gay, I suppose you are what you think you are.

Of course not! Everybody knows that it only counts as "gay" if you take the guys you fuck to dinner and a movie first...
