It's purpose is to remove females' desire for sex, therefore preventing them from cheating on their husbands. As a "bonus" it makes sex painful for the females. Just good ol' islam partying like it's 1399.
Making a small nick in the clitoral prepuce doesn't do anything of the sort.
Yes, there are various forms of FGM, and not all is removal of the clitoris or labia. So you can't say that's the purpose of it..there are a variety of sociocultural factors. Many cases of FGM are not as destructive as male genital mutilation that is far more commonly practiced.
The WHO classification:
Type I — Partial or total removal of the clitoris and/or the prepuce (clitoridectomy). When it is important to distinguish between the major variations of Type I mutilation, the following subdivisions are proposed:
-Type Ia, removal of the clitoral hood or prepuce only;
-Type Ib, removal of the clitoris with the prepuce.
Type II — Partial or total removal of the clitoris and the labia minora, with or without excision of the labia majora (excision). When it is important to distinguish between the major variations that have been documented, the following subdivisions are proposed:
-Type IIa, removal of the labia minora only;
-Type IIb, partial or total removal of the clitoris and the labia minora;
-Type IIc, partial or total removal of the clitoris, the labia minora and the labia majora.
Type III — Narrowing of the vaginal orifice with creation of a covering seal by cutting and appositioning the labia minora and/or the labia majora, with or without excision of the clitoris (infibulation). When it is important to distinguish between variations in infibulations, the following subdivisions are proposed:
- Type IIIa, removal and apposition of the labia minora;
-Type IIIb, removal and apposition of the labia majora.
Type IV — All other harmful procedures to the female genitalia for non-medical purposes, for example: pricking, piercing, incising, scraping and cauterization.
Edited to add: ALL of this, whether on male or female minors, is a violation of the minor's human rights.
