I actually believe this and I think it has to do with humanity and life on this planet in general coping with sexual dimorphism, we have to contend with things most people take for granted and are taught to never question which forces us to develop a different kind of insight

Tranny legends exist from prehistory and some goddesses like Isis apparently let crossdressers perfom rituals. I'm not the most experienced pre-historian or whatever but even I could name a few and not even remember half of the ones floating around my field.

I have a reputable history of around 10 AD and it mentions that in Mesopotamia there would be boys that castrated themselves and presented it as an offering. The temple would then take care of the neutered male acolyte and let the initiate dress as female and serve with the women in the temple.
tl;dr life finds a way
But it's worth mentioning that I suspect these old temples in all the cities also functioned as hospitals with healers using medicine stocks. Sort of like if modern nuns were more agrarian and less Catholic. Anyway these are from reliable historians though they had a pro-Roman perspective.
