Is it normal that i love to get abused during sex?

I have an insane sex drive to the point where I masturbate and look at more porn than my fiancee. And we still have sex two or three times a day. I especially enjoy getting mouth fucked, anal sex and being tied up, blind folded and video tapes doing all these things. I'm afraid to ask my other friends what they think because it's a bit embarrassing how rough I can get in the bedroom and the only two people i asked hypothetically said it's demeaning to women. Normal?
