If you want a traditional society, the following steps will be necessary...

• Ban dating apps, require that the current dating companies move to in person buildings that emphasis relationships over hookups.
• Purge the education system of leftist indoctrination and replace it with education that promotes family values, monogamy, and women's role as homemakers in society. Do not promote monogamy from a prudish standpoint but rather teach adolescents all the benefits of it. Monogamy is actually a lot more fun than promiscuity is. People have simply been misled by the media.
• Place a bachelors' and spinsters' tax on unmarried individuals above the age of 25.
• Regard S&M and rough sex as being the same as battery/assault and do not allow "consent" to be a valid excuse for it anymore than we allow two angry guys to wail on each other outside a bar.
• Legalize prostitution and set up strict regulations that blacklist any individual who harms the prostitutes or engages in perverse actions.
• Setup agencies that find husbands for prostitutes after they go into retirement.
• Ban abortion on request.
• Legalize the sale of softcore pornography to teenagers, but restrict them from viewing hardcore pornography. Then require that hardcore pornography be something you have to pay for as an adult with a valid drivers' license while softcore pornography remains free for anybody with an internet connection to view.

As for why I suggested that last one. You want to crystalize the arousal patterns in adolescence. There's a good bit of data to indicate that what you jerk off to as a teenager is what you will always find arousing. So what we do is simply crystalize vanilla sexual attractions and prohibit them from viewing perverse material. Then once they are adults we make perverse material inconvenient to access so that softcore porn remains the standard.

By softcore porn, what I mean is that they wouldn't view anything more hardcore than something you'd see on an episode of Game of Thrones. It would basically just look like a long sex scene from an R rated movie.

I know what I've suggested here would be controversial to both sides of the aisle, but I want to remind you that you do not succeed in creating healthy sexuality by shoving it away and locking it inside a closet. Doing that creates Saudi pervs who run sex parties in hotel rooms so disgusting and perverse that hotel staff refuse to clean the room because there's literally shit dripping everywhere.

You have to accept that the sexual instinct is a powerful drive that you simply cannot repress. You have to take charge of it, and tell people where it is okay to direct that sexual instinct and where they are not allowed to direct it.
