I think a lot of times people with a low Sexual Market Value try to have high standards in order to try to make themselves look like they're worth more than they are. "I only accept dudes who are 6'2" and have a 7+ inch dick. If you don't have any of those then don't bother talking to me." It's more common for me to see fat women having those standards. I think it helps to boost their ego. Meanwhile hot girls just KNOW their value. They don't have to artificially boost it by imposing arbitrary standards.
