I'm am really feelin' about half of the sentiments in this thread.....
In addition to some of the more astute posts in this thread, I would like to add/reiterate that people need to consider the motivations for their preferences. Black men are either vilified or fetishized among mainstream gay culture. Seems like there are too few people who look at black men any other way.
When I was in school, I got attention from ONE gay white dude. Any other time I went to the gay mainstream parties, I would just get stared at and ignored. I didn't like the same things the gay white folks liked -- I liked what straight black people at my school liked: hip-hop, parties where you danced instead of get wasted, and baggy jeans.
Now, five years after graduating from college, I can say that my mind is open to men of any ethnicity, but for a long while there I was like to hell with white dudes, cuz white dudes said to hell with me.
Now, on a more specific tangent.... I didn't like white guys because physically they weren't enough for me. I like full lips, big thighs, and big butts. I like full, rich skin tones. And I like curly hair and dreadlocks.
However, I could fall in love with anyone -- I've certainly dated thin dudes with no ass and black dudes with thin lips.... and I've gone out with white dudes. Never white americans, but they were white nonetheless.
Anyhoo..... yay, this was my first post.
