I guess it depends what you're comfortable with. On one hand, I could care less if people call me by my male name (I know a few girls with my male name, after all). OTOH, when someone calls you "him" when you're obviously presenting as female, that's a slap in the face, and calling you by your male name could be perceived similarly. Then again, I've also had people buy me multiple drinks and still refer to me as "him," and I really can't get offended when someone is being nice and happens to be kinda clueless.
I've always had TG feelings but I never went by a female name till a couple years ago. I don't really think it's that big a deal. We're not going to revoke your CD card if people like to call you Bob.
If you're uncomfortable just let people know. Say you think it's safer if they leave your guy name out of it.
