My main one is disembowelment. More specifically, disembowelment that involves a male victim at the mercy of an attractive, sadistic female.

I have this fantasy of being gutted in combat by a superior female opponent. After a long, sweaty, erotic struggle, she would stab me in the navel and rip my belly wide open, spilling my intestines. As the last of my strength leaves my body, she would castrate me, claiming my dick and balls as a trophy. She would finish me by hanging me with my own intestines, displaying my mutilated body for everyone to see.

So, as you can tell, I''m a pretty big masochist. Some of my other fetishes are:

-belly torture (with me on the receiving end): punching/kicking/kneeing/etc.
-feet (female only): footjobs, smothering, ballbusting, trampling
-castration/penectomy
-ruined orgasms/denial
-erotic wrestling
