Those of us who've been out a few years and can do this should be a bit less casual about this tbh. The Real Life Experience inflicted on us by gender clinics to get access to hormones was designed to kill people or force them back in the closet because these fuckers know hormones work.
I cannot emphasize how much of a non-issue this is. I use the women's. Doctors ask when my last period was. Airport security looks back up at me when I hand them my passport. I have navigated life smoothly as a woman for years, and I am only endangered by the ideological fixations on denying that.
