I mean, I largely understand how the instinctive sex identification works on a physical basis, and it is just too much shit you can't block. But the mental part is still quite mysterious to me. Maybe I can block certain perceptions, which would in combination with MtF women who were androgynous to begin with, prevent myself from making the fatal realizations on the long run. Maybe I can become semi-bisexual. It is still somewhat more probable than finding real women I am interested in.
Pictures make a lot of difference:
The only really obvious giveaway is the large forehead and the somewhat thick hair (despite the fact that you obviously need a male brain to compete in the top league of Starcraft). But who knows with certainty .. the first good female gamer prodigy maybe?
Now with the very clear frontal real-life pictures, it is impossible to not see a guy who went on HRT after puberty ... or somehow has high estrogen levels. It will probably never work. But most transsexuals get HRT after puberty, because of legal reasons.
Also, this woman:
Gender detects as clearly male. But I would believe she has more pressing concerns than to be transsexual. Maybe intersex? Or just the mere chance of genetic randomness? Could be XXY with HRT, but then not really clear. The mysteries of perception.
