I find it irritating that many MRA's seem to think FGM is far worse. It is impossible to make a direct comparison because the physiology and sexual responses of male and female genitals are totally different but there are some useful reference points. Firstly the clitoris has 7-8000 nerve endings the foreskin has 20,000 so removing the entire clitoris would be removing less than half of the nerve endings than removing a foreskin would.

The only function of the clitoris is for sexual pleasure where as the foreskin has multiple functions such as providing a natural gliding motion during sex, storing natural lubricant, preventing keritonisation of the glans(all of which combined increase STD/STI transmission). It also protects the head from sensory overload during sex which causes a very unpleasant sensation after ejaculation that makes you want to immediately stop/disengage(which you circumcised guys will know about although maybe have thought was normal). The foreskin engorges during sex providing extra girth, you lose the ridged band which stimulates the G-spot and you lose the 5 most sensitive parts and 70-80% of the sexual sensitivity of the penis. It also increases the rate of issues such as erectile dysfunction and premature ejaculation. If done badly there are many other issues it can cause such as curvature of the penis, hairy shaft and uncomfortably tight erections.

I am not saying removing the foreskin is worse than removing the clitoris but I am not saying it isn't either. It certainly isn't self evident one is worse than the other.

Then we get on to the more serious forms of genital mutilation because I can almost hear the refrain from those desperate to woman worst "but what about infibulation" well yes that is really bad although much rarer than other forms of FGM and at least partially reversible(the woman would still be missing a clitoris and a large portion of labia) you could make a strong argument it is worse than circumcision. Is it worse than flaying or bifurcation of the penis though: https://www.thesun.co.uk/news/8938980/penis-skinning-ritual-african-youths-foreskins-sliced-peeled-infections/http://www.bradshawfoundation.com/unambal/circumcision_initiation.php

In short I don't think you can argue FGM or MGM is worse, I don't know why you would bother either and it irritates the fuck out of me to see MRA's dismissing the severity of MGM, women worsting or regurgitating the standard bullshit you are fed about how FGM is way worse like you have a clue what you are talking about.
