They think they have round asses with small waists and big tits. Well no only 8% of women have an hourglass figure. 39% of adults aged 18 years and over were overweight in 2016, and 13% were obese. So I'd say out of women aged 18-30 atleast 10%are overweight. And then theres the fact that most girls are average looking.

Tdlr: Only a small portion of women aged 18-30 are actually hot
