Is this alright...?

I'm about 18 , a black female, for the longest time, I have always, always had a preference for white guys (only dated whites, really. Don't turn this into a race discussion, please.) I'm an independent woman, very sure of myself, but for some reason, I'm into really hard racial play and bdsm, (at the moment, I'm actually dating a Dutch guy) and we do a lot of role playing, which mainly involves uniforms, ropes, and a gag. I like to be treated like crap, and sometimes, I like to do historical role play with him, along with verbal crudeness, physical mild pain, and humiliation (I'm a sub l, and he's the Dom) but in general, I sort of enjoy being bottom, and imagining I'm in some sort of old era with him, and he takes advantage me and we like to use slave/master role (please don't reprimand me; both my parents are from Senegal) and in general, I enjoy doing racial role play and bdsm with generally white guys, and fantasizing about it.

My question is: is it normal I enjoy this stuff, and am I alone? I don't anyone to make me feel bad
Not necessarily is it normal, but more 'would you do the same,' or 'am I alone?' sort of thing.
