Why do only overweight black/white girls like me?

All my life it's been only overweight black/dark skin women and overweight white woman. lol I'm 6'0, black, Kanye west color dark, nice, polite, and I've always thought I was attractive! (I'm very honest, if I was ugly I would say!) What is it about me that attracts these women? Thin, beautiful woman seem to flirt with me and stuff but thy never make their crushes on me as obvious as these women do...
