Psychologists have found that adult females who have prominent chins are more sexually active than those with softer features, yet are less attractive to men looking for a long-term partner.
Larger chins on women are often caused by a high level of the male growth hormone testosterone, present in all women in various amounts.
The hormone also increases sexual assertiveness in a woman, a tendency more commonly attributed to males.
It was concluded that men will shun women with such masculine features when looking for a long-term partner because they fear being cuckolded.
People hate cheating spouses because they’ve violated the most sacred human contract there is: to work together to create a family where each member is defended against the world. As we can trust our fellow citizens less and less, this becomes more important.
Masculinized women, in addition to being a blight on the workplace, are more likely to cheat. They lack the complementary force to a male that makes a marriage work. So now you’ve got a problem. Men who are in touch with their instincts avoid them so they can have functional families instead of joining the world at large in its dysfunction.
