Mine are exactly the same, and I'm MTF.
Somehow the kids in my grade 7 class heard of this, and had to check everyone. I was singled out and embarrassed, but my feelings were already confirming it. The thought that everyone might "see" me was disturbing. How could I go through life if a visual test would reliably call someone who is in the closet out?
Luckily the kids were on to some other game soon enough.
Lauren, and mostly in the closet.
PS I hope this doesn't bother others, but I heard that FTM TG people can be identified by their teeth and the shape of their hips. Don't know just exactly how. If it was easily "seen" and it was generally known, would maybe parents and doctors then notice and encourage experimentation? That might be a better world.
