If not for the pill
it was a study done that showed that women find feminine men more attractive , except when the women are ovulating.
(one guys face cut in half, 2 right sides, 2 left sides put together.....one face will have a bigger jaw, bigger brow(1 more masculine, 1 more feminine).....women asked "which is the more attractive twin?" 80% said feminine male, except the 20% that were at or near ovulation.
The pill makes women's bodies think that they are pregnant, which means that they do not ovulate.
This means that Sexually active women are attracted to more feminine looking men......then Men adapt and wussify to have sex.
