Bah, if anyone 'goes to hell' (closer I think is to be left behind) it will be for your totality of existence upon this planet, not just the actions of any single life.
But, transsexualism a sin? *cough* Uh, no.
Any situation you find yourself in that is not of your doing is no sin; How could it be?
Hug those that call you a sinner, and sorrow for them for they do not understand.
