I find it a mystery why so many nerves are there, as well as why they were positively selected for. Enough so that human women have them with huge variation in shapes and sizes but they are there.
The idea of it being a pain killer for birth but requiring a vibrator is interesting, because I don’t think any culture developed clitoris stimulation as a child birth helper. If it did help I would expect it to change birth outcomes and thus being a source of positive selection.
The only thing that bothered me is that gender affirming is in fact an amputation, because they gave their clitorises to science. It even took me a while to understand what the term “gender affirming surgery” meant.
I thought that the clitoris contains all the nerve endings that would be in the male penis, just in the smaller area vs being spread out over the entire penis and penis nerves are selected for to encourage male mating.
Good point on the first paragraphs. The why seems to be that it’s mostly about pleasure.
Although not essential for survival, pleasure seems to be programmed in us as a species, so the body evolving this to give women the balance of a complex pleasure organ to make up for the pain — in so many levels — they go through during birth.
So maybe nature was like “they suffer a lot during birth and pregnancy, let’s give them a clitoris that gives them REALLY good pleasure that the male counterpart won’t be able to ever experience or comprehend.”
