(1) it is a sex change operation, please do not misrepresent modern genital mutilation. Sex is a biological phenomenon to do with reproduction and, simplifying a small bit: there are two sexes, male and female. A man whose genitals are mutilated does not become a women (i.e. gains the ability to give birth to children).

(2) the purpose of modern genital mutilation for the mutilatee is to facilitate sex fraud, and for the mutilator is, one imagines, money.

(3) if believe someone at that age is mature enough to understand the implications of modern genital mutilation, you will have to face the question why you trivialise it. Your writing here may, directly or indirectly lead to more modern genital mutilation. Speech has consequences.
