I don't think I've ever actually had someone come up to me and talk about lesbians or call me one. Although I get called fag and dyke most of the time, mind you those aren't really civilized conversations. My aunt uses the word lesbian all the time, but I know it's only infront of me, so either she is a very cruel preson and likes to see my wince at the word, or she wants me to fess up that I'm gay.
In civilized conversations where I'm talking about my sexuality, I usually say I'm gay (I only say I'm a dyke when I'm with close friends, or to get some creep to go away) but when I'm just randomly talking about my sexuality, it is that I'm gay.
And I have finally gotten over the whole "that's so gay" I heard it so many times I just started saying "that's so straight" people get irritated by it actually...aha.
