Actions speak a lot louder than words.
First you have to realize that most CDs I've met have been in clubs that have drag shows which would mark them as gay bars in most people's book, so I'm not saying my experience applies to everyone.
But anyway, most CDs I've met have found time to mention that they were actually totally hetero guys (odd how many volunteer that info, seeing as I've never found myself asking).
And yet, these same CDs have also almost always made some kind of sexual advance towards me by the end of the evening, whether it's grabbing at me or trying to kiss me or just suggesting that they'd like me to do ... uhh ... something to them, or them do something to me.
I've often found myself leaving tables with CDs and hanging out with drag queens (ones who are 100% up front about being totally gay) just because they have better manners. I've witnessed astoundingly inappropriate (not to mention gay) bahavior from CDs who claim to be totally hetero.
Personally, I really don't care what people think of my sexual orientation. I'm attracted to girls, but I guess I've found myself attracted to a guy now and then. Hey, if he's doing a good job of looking like a hot girl, I'd feel pretty homophobic if I wasn't attracted to him. So I guess to be honest I'd call myself bi. But that's not something I let get too far very often. I've made out a little with a few CDs and queens, and I'm not a big fan of stubble, even if it's hidden under thick foundation.
But at the same time, I do like guys hitting on me when I'm en femme. I've never been hit on by a guy that I didn't think I could pretty much flatten if he got too persistant, so it's never been that uncomfortable
