I am a little surprised by the results of the poll here. Of course, it is in no way definitive but... my experience has been that most TVS, CDs have been 'straight' and liked women sexually.
My own thinking is that if you wanna be a girl then you want a man. That is where I am coming from anyway. I want to dress as a slut, or sissy, or classy lady and service a guy. I am lucky to have found this but... a slut always wants more ;)
