I get turned on by violence?
So I would like to know if this is something normal. I have a girlfriend which I am sexually attracted to. I usually fantasize intercourse with her but the circumstances are a bit different from some other people. I say different because in my mind, the "foreplay" would be to strangle her, stab her, and then decapitate her. The most important part is the decapitation as it really turns me on and I usually imagine myself "doing" her after I decapitate her and stick her head up on a pole. So what do you guys think? Normal or not?
P.S: If she was somehow still alive after decapitation it would be even hotter.
