I'm gathering that the shared experience here is that often we are afraid to just use it regardless of how we present as female, and that we sometimes underestimate how unnoticed we might be if we try. I think when we look in the mirror as we transition, we do not see what others see. We're harder on ourselves, and it's hard to be coldly objective. We worry about fooling ourselves. We also are understandably a little risk-averse given that we get so much grief as a group, and the publicity some get when they are confronted.
I'm not hearing that many here have had problems, which is encouraging. Confidence and common sense seem to be the guide everyone is sharing.
What has been a little interesting for me is how the men's room now feels so off limits, as much so as women's was before I ever started.
The other interesting first for me was when I went in with my mother for the first time. I don't think she expected it, but she was very cool about it.
