Is it normal that "normal" things don't turn me on

I've been told most things like making out, porn, getting eaten out, blowjobs, sluts, and manwhores are supposed to turn a girl on, but I've never been turned on by that sort of stuff. Most of my fantasies involve myself filling the role of a submissive with a female or male dominant. These can entail orgasm control, them watching me masturbate, etc. When I touch myself and try to think about normal sex, it doesn't work for me. I also have some rape fantasies, but they're with attractive partners who would never really hurt me. Also, I'm disgusted by porn but erotic stories really turn me on. Is this normal?
