I think your personal experiences have biased you to having a certain interpretation of beauty, that's a common but very one dimensional interpretation. To me, it's all relative. No one and nothing is absolutely attractive or beautiful. One thinking feeling thing finds another beautiful for any number of reasons, not just evolution, procreation, or culture. I've known beautiful people, beautiful to me, and it wasn't cause they had big tits. But then, I'm not the ruler of words, just sharing a thought in return.
