I have met very attractive people who fall into either one of those categories, I guess. Personally, I prefer women and part of that is that I enjoy femininity. There is enough variety in female genitalia to satisfy me, though I mentioned elsewhere that I ran into a dude that preferred trans women because they appealed to him physically and he was able to find partners who enjoyed and understood traditionally male pastimes and perspectives. I never asked him what his thoughts were on females who represent themselves as male. I guess I can understand that some people are trans, but personally I can't imagine having a relationship with a trans woman, but I say that because I imagine a lot of baggage and while I realize that everyone has some, I don't have any idea how that might influence any level of relationship I might have with such a person. Anyway, I am still too fascinated with my own dick to pay attention to anyone else's.
