Waist - to - hip ratio relates to sexual behavior such that
females with more
desirable ratios have a greater number of sexual
partners, have intercourse at an earlier age, and are more likely to have sex outside of their primary relationship (translation: they cheat).3 So why is a.70 ratio so appealing in women?
Dissatisfaction with a less sexually
desirable partner when a woman is near ovulation may have encouraged cheating among our
female ancestors, thus increasing the likelihood of conceiving children with sexually
desirable partners, Larson told LiveScience.
