@matana I agree 100 percent. This is a perfect example of crazy people just trying to normalize insanity. There is no reason to let kids of ANY AGE to hear the idea of bodily mutilation.
the author is not trying to normalize insanity. The author has a yandere fetish (understandable) and a genital torture fetish (wtf do these freaks come from?), and is trying to give future yandere gfs ideas like "why aren't you sympathy-bleeding like those noble tribesmen do?!"
