Welcome to the club.  You'll find that the vast majority of us here self-identify as hetero.  I've never had a homosexual experience either, and I have been with many Tgirls.
You'll also find some who will say that statement is delusional.  But you get to define yourself.  Nobody else does.  It can be confusing as hell but be proud that your sexual identity is not easily defined.  Fuck em.
