Normal to want this?

I am a really confident woman and I love being outspoken and strong. My family and friends always call me really independent and I consider myself a feminist and stuff. But the things is...in bed I have this strong desire to be the submissive one. I'm really kinky. I want my man to be dominant and talk dirty to me and be rough with me. I'm talking tying me up, making me beg for it, slapping me, etc. I want to have really rough sex. Is this normal...you know to be one way in real life and then the total opposite in bed? Just asking. Please don't give hate. I've just hit my twenties and I don't have much experience so I'm asking.
