Accidently hit send without being able to finish editing the title. Anyway what I'm asking is being that most "average" women per day can find sexual partners pretty easily even compared to an attractive man, why do folks feel beauty standards for women are high? Or that men's physical requirements are too high? I've seen the opposite. Ladies educate me.
