80% of women are attracted only to the top 20% of men, while most men are attracted to most women. Even a man who's a 10/10, who's interested in casual sex, is probably going to be interested in having sex with a woman who's a 4/10. The opposite is never true. Women only settle for men close to their level of attraction only when they are looking to get married.
