We used to have a thing called no sex before marriage and it worked pretty well for people smart enough to follow this rule. Not only this gave many men an incentive to get married since this was the only way to get their dick wet, but it also helped reduce the amount of children born out of wedlock.
The only way to fix our current cultural predicament is to normalize beating women again. We can still beat children because they belong to the parents until they are of age, and that was also the argument used by wife beaters. Its not violence when its done out of love and women require a lot of discipline, especially if you marry older women in their mid twenties when they had a lot of time to get brainwashed with feminism and other jewish tricks.
Banning all forms of chemical and surgical birth control will be of great help. You shouldn't give the woman that you love ingest a bunch of harmful chemicals just because you want go in raw. Women have no integrity or shame, they will do anything as long as the men around them enable their behavior. Men need to start controlling their women again and it will be easily fixed in a generation or two.
