So, to be realistic and wanting food on the table more than a surgery is to kid oneself?
Surgery is scary, it's invasive, dangerous, painful, and insanely expensive.
And no, I don't think that contents of underpants is the definitive definition of male vs. female, because if it was then all Transsexuals are "just kidding themselves" when they use those terms to refer to themselves. If you "Need" a penis to be a man, then by that definition, I will never be one. Why? Because there's no surgery available to me that has a result "good enough" for me.
I am not qualified to diagnose GID, or tell who is or is not Transsexual, and with such limited information, no one is.
