There's a book; can't remember title or author but it came out in the last 10 years or so: Somebody have it or know it??
Anyway, it explains how the male population doesn't have just two or three sexual orientations, but five or more.
And furthermore, just because I might like men and their dicks doesn't mean there's much Girl in me. Still there's some truth to it. I mean a little:
Men have nipples. Men are, embryologically speaking, ex-females.
But I am one of those gay guys that has little identification with Marilyn Monroe and similar Divas. I have very passing interest in what they are showing on the High-Fashion runways. I'm a bit of a slob if I'm busy.
I'm just not a very good woman. And the identification of gayness with femininity is baffling to me much more than it makes any emotional sense. But that's just me. And a lot of other gay-guys.
