I also think the times we live in have something to do with this too. I'm a professor (as the screen name implies), and I remember how it was almost unheard of for anybody to be out -- much less bi -- in public. Twenty years later, students are all over the spectrum -- gay, bi, straight, fluid, pan-, the whole nine yards -- and there's no shame in that being known. I have looked at a few dudes over the years and thought, hey, they're good looking. In the past, I would have been nervous about acknowledging that; now, I don't care. In the past, I might have had some worrisome thoughts about looking at dicks on a big dick site; now, hey, it's no big deal. I suppose I've grown more open-minded about my sexuality and less worried about the consequences of that.
