Ever since i was 8 or 9 i had fantasies of girls in perilous situations. I have a memory of watching the three musketeers anime and feeling very excited when the evil woman had kidnapped D'artanian's girl and had her bound and gagged inside a burning shed. This later developed into darker fantasies, then added bdsm to that once i discovered it later in life.

There's definitely some moments when you're like, did this cause my fetishes, or were it just already there and it just "kickstarted" it.

I remember seeing a scene (i think from "the mummy") where a guy gets mummified and buried alive. It was kind of a shock to watch, but W
when i put a pretty girl in my mind in that scenario, i had the biggest boner.

Once i found an guro-esque comic hidden in our house. Knowing now, it was probably like one of those italian erotic thrillers. I don't remember what i saw, but i remember it was shocking and sexual.
