So when you say that you were heterosexual before and still are after transition, you mean you were attracted to women and are now attracted to men? Or that you were always attracted to men because you've always been female, but that people mistakenly read you as homosexual pre-transition? Or do you mean you've always been attracted to women, and don't care that for any observer who accepts you as a woman that you now appear homosexual?
No, that's not the least bit ambiguous.
I didn't mean that I was confused about my orientation, just that the words to describe it are confusing when you know I've transitioned and aren't sure whether it's relative to my assigned sex or gender identity.
