I am black girl, why am I not attracted to black men?

Hi, I am 21 years old black lady. Ever since I became interested in opposite sex, I'd always been attracted to WHITE males only. I dunno why. I dated 4 guys, all of them were white. I went on a date with couple black guys, but it usually ended after first date.

I even lost a friend over this, she told me I'm bad sista, racist, who*e and I should hang out with whiteys...

I don't know what is wrong. I guess it's the way they treated me, they spoke, acted... I really wanna be a good member of our community :( Is there something wrong with me?

Thanks for your opinions. Apart from being called "bitch for rich white dicks" I got much worse PM, but I now feel confident that nothing is wrong
