It takes more time to keep an elderly uncircumcised woman clean than it does to keep an elderly uncircumcised man clean.
I wonder what parts of a woman's genitals your friend would recommend cutting off so that it is easier to keep elderly women clean?
Are you talking about them giving the old women a douche? That is at least a standardized way of keeping them clean. I’ve seen nothing marketed in the United States for men that would be comparable.
