I agree that sexual orentation and gender identity are two seprate issues. I would not agree with including CDs and TSs as being both necessarily identifying with the opposite genetic gender. A TS does, definately, but as CD is a practice engaged in by several various motivations, CD cannot be talked about in such a general sense. CD is a SYMPTOM of several different dissimilar conditions, and not a condition in itself. I think that a degree of TS may be the only condition wherin the person actually idintifies with the opposite gender/biosex.
Other forms of CD may have a sexual connections, but not necesarily connected with identification with the opposite gender/sex. These include fetishes, transference, S/M and escapisim. These folks CD too.
I say Hetrosexuals are those sexually attracted to the opposite BIOSEX rather than gender. And Homosexuals are attrected to the SAME biosex---these are the correct medical terms, and can serve as a basic platform to branch the terminology from. Might a hetro man be attracted to the same sex but an opposite gendered person?----yes, because a bio-hetrosexual is programmed to be attracted to a person who LOOKS like a woman, whether the person is really a woman or not---Thats the hetro drive doing that. The converse may also apply to a homo man.
