I've done a lot of thinking on the subject. I am attracted to women while in drab, and mostly attracted to women while in drag. I do have occassional fantasies about being with men while dressed. But only two things happen, I'm either on my knees, or having intercourse. At no time do I ever think about kissing men. Or caressing their bodies. It just doesn't do anything for me. I've even seen gay porn, and it did nothing for me. The porn that does interest me is lesbian, sissy with woman, or "once in awhile" a sissy with a man who usually has a female partner there too, a threesome. If the porn is a man and woman, I'm jealous of her not him. Somehow, my desires are always woman centered. I'm with her, or I am her. What does this say? I'm certainly not gay, I'm probably not bi. Somehow, inside me, there is a female sexual identity as well as a male sexual identity. I think with CDer's, the female comes out sexually at times. To me, it's clear that this definition is the "best fit" for crossdressers. I think you're only bi if you like men while in man mode too. If you can't cross that boundary, I don't think you can call yourself bi even if you commit a generic bi act with a man while dressed.
