True what I mean by srs is if someone where to question your identity you could prove it. If some stated a mtf post op wasn't a female if she striped u couldn't tell unless you did a pelvic exam. A post op mtf could walk into a publi locker room butt naked and idk but I do t think anyone would question her. In the showers most ppl arnt thinking weather someone is trans. If a ftm post op walked into a locker room naked ppl would no something is wrong.
