When I was little, I looked like a girl and people treated me like one. Only my mom ever argued about it.
Later, I could pass for a girl and was often still treated like one, but I got beat if I asserted I actually was.
Post-puberty, nobody took me seriously as a woman, but they still often subconsciously treated me as one.
With a few minor adjustments, it became more like 50/50, but the failure mode was extremely bad.
Post-HRT, everybody went back to seeing and treating me like a woman.
