It's subjective. What I think is extremely beautiful you may think is dog balls. And you put the caveat of, "natural" in there, but what difference does it make if her hair color comes out of a bottle or that shes wearing colored contacts? Why do you have so many conditions for beauty? If you ever find a women that meets your expectations she could be a real asshole, then what? And that doesn't speak anything to your own level of attractiveness, which is largely a function of how much money you've got. But all that aside, blue eyed blondes are my least favorite type, and are you limiting your query to women in porn or are you looking to cast a wider net in your search?
