because when in the fetus, the embryo starts out without a gender. Because of this, the scrotum skin is made up of the same skin as is the labia. We all have more or less the same parts arranged in different ways. (scrotum-> labia, glands-> clitoris)

gender is determined by x or y sperm gender is set in stone at fertilization

not him, but the true effects of the Y chromosome being present manifest themselves AFTER the skin is formed, therefore before that point the embryo is on the outside genderless

>> No.9954267

>>9954041
if the embryo has an xx or an xy it is not genderless, it is simply not fully formed yet

embryos in their earliest stages for all mammals are indistinguishable, yet they are clearly human pig or dog at the moment of fertilisation, even if they superficial similarities as they are still forming

This.

Also, glans penis and clitoral glans are made form the same tissue. Hence female clitoral sensitivity is way up compared to the male glans (roughly same number of nerve endings on a much smaller area)
