There are very basic things that have been hardwired into us as a species for hundreds of thousands of years. Women are attracted to men for three reasons: One, them signaling their ability to garner resources in the future and two, how smart they are. If you're an asshole, over the long term, people don't want to mate with you. Men are attracted to women on a much more one dimensional level. And specifically, women who appear to be fertile are young women. The world is sort of optimized for those two parties. It is gross and it is 100%. True.
