I had a "men's washroom" experience too lol, so it was a year and half ago, I had med-length hair (for a boy), I was wearing a hoodie and tight jeans and a pair of converse, I was still presenting myself as male so naturally I went In the men's room, While I was just done washing my hands, a guy came in, he looked at me and he said "wooow is this the women's room!?!?!" I just ran out the washroom, and I had mixed feelings, on one hand I'm happy that someone thinks I'm a tomboy, on the other I was super embarrased... And I tried to avoid public washroom since then, I'd go to the one for disabled people if possible
