I haven't had a drop of T, and I get sir'd, he'd, and young man'd left and right. I have my hair styled in a masculine way, wear men's clothes and men's cologne; that really seems to be enough for people. I've watched men throughout my life and mimicked the way they carry themselves and speak, so that may add to it. But one look at my chest, unbinded, and I'm clearly female bodied. So more than often I get the "Hey buddy..I mean, lady". And its like damn...
I almost passed.
