Is it normal for a white woman to crave rough inter-racial sex?

I am a professional woman in the education field. Physically I am petite, a size 2 and only a little over 110 pounds. Although I am generally conservative in my life, I am sexually submissive and enjoy submitting to Black men in what is commonly referred to as "rough sex". This usually takes the form of fantasies that I enjoy, and while we usually employ a Safe Word in case things get out of control, there have been times when the circumstances do not allow this, as when I'm having sex with a Man I just met and haven't explained my desires....Black men don't need it spelled out for them, and I'm sure that to them I am nothing more than "a white piece of ass". The thing is that these casual sex encounters, where I have no control, are the most exciting to me, perhaps because of the fact that I truely have no control and they tend to be a little rougher....I don't mean really getting hurt or injured, but I have had bruises on my bosom and body, but these men are much bigger than I am. The inter-racial part is very important, I have many fantasies that revolve around the fact that the man is Black, fantasies like him being a Slave and me being the White slaver's daughter. The men I engage in sex with are not the educated professional men I work with, but usually men I have reached either casually at a bar, or men from prison counselling sessions I am involved with. Do other white women share these desires? And how do white Men view this type of sexual activity?
