There were times in the past, long before I considered transitioning, when I was "correctly gendered." Even before I grew my hair out, over 20 years ago now (!) I kept it at least halfway down my ears, though it was a guy's cut. Seen from the back, I'd occasionally be called "ma'am" but that was always immediately corrected when I turned around. It was still a thrill back then, though I couldn't tell anyone about it.
Since going full-time, it's so important to me to be correctly gendered that I'm still a bit terrified of trying male-fail. I refuse to go out, even walking the dog in the neighborhood - where I'm still constantly misgendered by those who've known me so long - without at least a little makeup and jewelry. It's possible my FFS back in December may have helped, but I still don't want to push it - I haven't been misgendered by a stranger in a very long time, and don't want to feel that sinking feeling now. Maybe after my upcoming facelift and when the hair grafts finally grow in...
