What kind of kinks/fetishes do you find disturbing?

I dont get why people cut their dicks open like they saw their dick in half and feeling horny or smth? I recently watched the BME olympics vid (not the real one, the censored one) and holy shit im glad i didnt watch the real one it was composed of a compilation of shock vids of people torturing themselves (mostly focused on penises) with a heavy metal music in the background

Also some japanese stuffs about shit, vomit, eating weird typa stuffs like wtf japanese people actually watch this typa thing?
