Among animal species, males are more sexually opportunistic than the females. Tomcats approach the females, fight for access. We have every reason to believe it is in our genes. It is explained by our unequal contributions to reproduction. A woman invests more in a child than a man.
Females invest more in each reproduction, so better to go slow and choose carefully.
Males invest less, so benefit genetically by being opportunists. While men dominate in industry and government, women dominate in personal arguments. The man who is comfortable offending women will get fewer genes into the cooker, and have fewer offspring. The man who is stressed when a woman is upset, and concedes, placates, or avoids the arguments, will stay on better terms with women and will have more surviving offspring. BUT females can take food away from males and shove males aside to sit in the shade.
