Skin color DOES matter in gay men relationship?

I won't talk about political, economic or educational but just social issue in gay men relationship. I used to have a personal color preference to my partner. Some people might say, "Well it's okay because people are more likely to get attracted to the same color." Well I would say, "No" because the ridiculous thing was that I was more into different color but not mine. Was it just my personal preference? Or was I a racist? I read from sociology book that White/Hispanic men are masculine, Black/Hispanic men dangerous and Asian men asexual. Maybe the book was just biased or over-described. I used to believe that the skin color issue plays the main role when people think of their partners because I used to be one of them. You can't really blame me though :D because our society was sending me hidden message that whites are most demanded in gay porn and even on craigslist ads saying "White/Latino only". Would they still be saying that it is just their personal preference regardless of skin color? Anyway I do agree that NOT ALL PEOPLE feel the same way. Some people wouldn't care about their partner's skin color, but they do have their personal skin color preference on their partners? I would personally believe that skin color issue DOES exist in gay men relationship. Please feel free and share what you think because I wanna know how people think of this issue. I wouldn't mind to get a negative comment or an argument.
