This story reminds me of something I heard years ago and that always intrigued me.
An expat friend of mine was friends with this very tomboy looking Taiwanese 'female', who was legally a woman: name, voice, ID card. But she often said she would rather have been a man, she had 'manly' interests and hobbies, she could easily have passed for a man if it were not for the voice, etc. I later learned that, let me quote: "when her mom was changing her nappy, she didn't know if that baby was a boy or a girl"... I didn't dare to ask more questions or, God forbids, for a quick look at the object of confusion...
That woman must now be about 40-42 years old, and was born in the South of Taiwan, so we can all guess the state of hospital/medical technology/mentality at that time. She wasn't dating anyone nor seemed to have any 'carnal' inclination towards either men or women.
I am amazed to read about Chuanzao's student case! I wonder why parents wouldn't want their kid to be operated at birth.
