you may not be in "transition," but that is the closest thing to what you are pursuing that a doctor is likely to have experience with. sure your case might be different. everyone who is misgendered is different (as is everyone who is gendered in a way he/she is happy with, but that's not the point). not wanting a gender is a form of misgenderment, i would think. you have to start somewhere, and someone who is comfortable with treating TG people would probably cut you more slack, even if you present something new.
