I am certain that therapy has come along way since my bout in the 80's.
I can't help you out much as I am not a therapist, just had an interesting life.
I am a male who would prefer to present female, it is not sexual as far as a fetish sort of thing. I am bi and have never been dressed for it with a male. Every once in a while a GG will really get revved up by it, most are not.
So I would ask this, are you turned on by a hot or certain kind of guy?
Do you fantasize about having sex with men while dressed, or not?
The answers to these questions are very important. A therapist will help you to figure yourself out a bit, but only you have the answers. Be certain as to what you want dear, the reality is often somewhat lacking compared to the fantasy time to time.
Peace
