"IMO, natural external genitalia, so that XY's who do not generate male organs during gestation will be classified as female. Every natural hermaphrodite should be assigned a state-funded lawyer from birth: it would be cheaper than making a statutory accomodation."

Interesting answer. Would you change someone's sex classification if, as happens in dihydrotestosterone-deficient males, their external genitalia changes at puberty? What if they didn't want to change it?
