For all for all intents and purposes I'm a /pol/tard (although I don't post there often anymore). However, for some reason I feel more attracted to asian and brown women than to whiite women and my only gf was a qt chink. I've tried unfucking my mind by not watching porn and so on, but nothing works.

This got me thinking about a more general question, how does the brain descide what it finds attractive. And I'm not talking about sexual selection here, but at a deeper level what neurological differences are there between people with different sexual preferences?

Has there been any research done into this topic, and if so, are there any known ways to actually impact what you get turned on by?
