I am turned on by the fantasy of being a body. An object. If I describe sexual things done to my body, it's not because I enjoy the idea of them (I really don't), but because I am turned on by the idea that, unlike me, the body will accept -anything-. I am not turned on by what's being done to the body, but by going into a trance state where I am not actually in the body. This leaves the body to whoever is near (or no one).
NOTE: everything I post is -fiction-, FANTASY, no different from violence in TV crime shows. I do not want to either look at real corpses, or to become one! My fictional murders, however graphic, only serve the fantasy purpose of making my body into an object.
People assume that everyone into this fantasy is suicidal or necrophiliac. I am NEITHER. It's just part of my sex drive, no different how someone may get off by, I don't know, getting peed on.
I kinda wish I didn't have this fetish, but oh well.
