Of course, but the comparison that is probably the most apt is imagine if everybody got their appendix removed at a certain age. Given the risk factors associated with each one, it would be a net negative for our society to do that rather than just pulling it out as needed. The cleaning argument makes little sense in the modern context, and of course STD spread is reduced, but it would be the equivalent of requiring every woman to take the pill until 20 to reduce teenage pregnancy, and anyway certain forms of FGM would also have a similar affect, but unlike circumcision they to not ascribe indirect benefits as a plus, while here they do. Its not without purpose, but it makes no sense to do a blanket surgery here.
