Being promiscuous is hugely advantageous for guys and getting better now that most women are foolishly following men and becoming more "slutty" giving guys more sexual opportunities. Their value has dropped significantly advantaging men and less obstructive.
Monogamy and marriage benefited the women more than men so looks like sexual incarceration is coming to an end.
Good news.
When women these days want to follow everything men do senselessly then why would anyone want to get married to them. There will be a significant drop in birth rate is the major effect.
