Men are about as faithful as their options. That's why high status men are "sex addicts".

To be fair, that also applies to women, it’s just that men always have way fewer options than women, and only Chad bucks that trend.

Also, due to men’s higher IQ (see any basic science) and higher levels of morality (see Kohlberg), men are capable of restraint and fidelity even if they are tempted with lots of options because they understand the value of faithfulness and promises. Women inherently dont.

Society solved the conflict between disparate male and female mating strategies with assortive mating, marriage, and shame. All of these things have been destroyed.

Sadly, it’s even worse than that. “Destroyed” implies the whole thing is gone and people are just doing whatever. The reality is that men are enslaved and second class citizens while women are the elites who do whatever they want.

Men are still expected to be faithful. Women however are encouraged to be whores.
