Jess, first, they don't say "I'm attracted to CDs when they dress female", they say (in the particular threads that I refer to) "I'm more attracted to a CD than a man". This seems paradoxical. Second, I call them men because they identify as men. If they didn't, they'd be TS or Gender Non-Conforming, but even then the latter is not a woman ... nor a man, for that matter.

And yes, gender is complex.
