Mostly, I prefer whites. So that puts me in the western European camp. But I have seen some blacks, Hispanics, Asians, Slavs who I consider really hot. Skin color or facial features don't matter as much as body type and characteristics. Then, too, do we mean physically attractive, as in handsome, or sexually attractive, as in let's fuck. Can't speak for anyone else, but for me it's not a simple choice. White, smooth, built: mostly. Others on occasion.
I see alot of models on sites like Flirt4free who are Russian and find them to be the most beautiful creatures in the world. It seems there are alot of young muscled lads in Russia. I also am very fond of Israeli guys who have muscular bodies as well... one of my greatest fascinations is this IDF soldier who is what I would call a perfect human.. a godly creature who I would give anything to cut out his heart
