I'm not convinced that having even more young people engaged in hookup culture and one night stands would result in stable marriages and families. You might want to screw some hyper-promiscuous party girl at the local bar, but you probably wouldn't want to marry her.
How do you think most relationships start, the guy is out looking for females and the female is out wanting to see what happens in her life.
Males and females can’t meet unless these guys get off their couches and go out to meet girls, the sex drive is supposed to make them overcome their fears and doubts and dislike of the humiliating snubs.
With your sensitivity to boys and girls meeting each other out in public, what is the morality of the boys sitting at home with their porn, avoiding females and instead constantly whining about the inadequacies of females? What does that lead to? A life of bachelorhood and isolation, and bitterness?
The males need to beat the bushes for female company and let nature take its course, it is how humans operate and how we find our wives.
