This makes me scratch my head a little... What is homo- or hetero-sexuality to a TS? If we're talking about an FtM "stuck in the wrong body" TS, are they homosexual liking men or women? If the mind is right, and the body is wrong, then the hetero FtM person (with male bits) would be attracted to others with male bits? Arrgh!! My brain hurts...
I think those links above will need thrice-readings to make sense. Kind of like legislation.
Satrana, per your thoughts on the -philias, I'm not sure one needs to take it so loosely... Isn't it more a -philia if the object is generally required for arousal? Then followed up with the term disorder if the philia gets in the way of normal function? if its really that easy for a philia, then what's the technical term for whatever-I-can-reach-philia?
