Dating other races

When I was younger I always dated white guys because I grew up in a pedominatily white town. When I went to college I found I was hanging out with people from all different races and discovered I had a higher level of attraction for black guys, but I don't really understand why. Is it wrong or prejudiced to feel this way? By the way, I'm a young white woman. I hear about a lot of stuff white people aren't supposed to do, but I haven't heard anything about this.

Thank you to the people who commented. I really appreciate the help. I've thought about why I might like them and how I treat them as some of you suggested. I think my main thing is I feel comfortable enough to be open with them and it's new for me to be able to do that. As for how I treat them, I try my best to treat them in the way they treat me which is well. I don't know the underlying reason for why they make me more comfortable, but I wish I did.
