I would like to find out what is that secret site where women have any interest in male mutilation. It must be on another planet LOL
According to my experience women have no interest in men at all besides when men give them attention. Women usually seem to be very flexible on what they like as long as it provides them attention, so they do not really care if you kiss them rape them or execute them as long as they are in the center of attention.

Exceptions happen from time to time but that's super rare. (and there is a suspicion that those women are "transgender" LOL)

I don't know how you are supposed to make people reveal their perversions in the real life so I never met anyone who is interested in guro or even plain bdsm. But speaking about people whom I know online, pretty much all are men, some seem to pretend to be women. People who are into male mutilation are also mostly men too.

I myself like both male and female guro. But I prefer feminine/young looking guys.
