Hello Moonkin,
I'm sorry I have no advice, but maybe you would want to read about
Amanda Lepore. Another article that might be interesting to you is about
Jeffree Star.
Shemales I'm not so sure about, I think that is just a term used in the porn industry where the individuals do not go through a sex change, but dress as female. I'm not sure if that is the same as transvestite.
I'm sorry I can't offer anything else. I wish I could. I hope you can explore this further with your therapist and s/he is understanding of your feelings.
Hugs

if you want them.
