I’ve never heard a woman say they did or would have their baby boy circumcised because uncircumcised penises are gross, or any other version of aesthetic reasons. The religious reasons are rooted in the patriarchy, as is the “need” to look like one’s father and male relatives.

In the case of female circumcision, it’s a way of enforcing the position of women as property, making it more apparent if she’s ever had sex so her virginity can be sold to her husband. In its most extreme forms it can require she be cut open in order to give birth, and resewn each time. It can block clumps of menstrual blood and lead to infection and sepsis. In less extreme versions it can prevent her from feeling any pleasure during sex, in order to prevent her from having any except that imposed by her husband.
