People aren’t just formless masses of pure reason floating through the world. We’re animals, and one of the most primal drives is to reproduce. That’s not society and culture that says sex is that big of a deal; it’s billions of years of evolution.

Even at an academic level, far too many people feel entitled to attribute absolutely every human outcome to society and culture.

Not only do we have philosophical, logical, and biological contributors affecting this, but "society" and "culture" can have logical and biological components as well. From a purely philosophical standpoint, what if I had come to the conclusion that a part of myself would live on through my children, and I am in despair at the lost opportunity to do do so? From a biological standpoint, I have lost access to one of life's greatest pleasures, but am also subject to the same physical drives without any release.

Now to expand that to "society," what fault is it of a partner who similarly has a philosophical drive towards procreation, or a biological desire for certain pleasure?

Some things just are blamelessly tragic, I'm sorry to let you know.

Is it society and culture or the single most important biological imperative our DNA can express, something hardwired into the parts of our brains older than life on land?

Certainly it isn't hardwired in any relevant manner, and people are in fact just fine not reproducing, see vasectomy.

Don't just repeat platitudes. People are killing themselves over not being able to have sex, or rather not being able to prove they're proper functional men. It has at least as much to do with social status as with actual sex.

Knowing you aren't held in respect by your peers doesn't cause depression because of culture or society - every single living organism with some sort of higher brain function gets "depressed" when its peers hold it as less valuable.

This isn't platitudes, this is science, and shows the solution likely isn't down the path of telling people 'losing your junk" jokes are harmful. Choosing to not have kids are far different than having that choice taken from you, and the most viable solution is likely chemical intervention.

For the record I agree with you (in contrast to some of these other commenters); sex is criminally over rated. There's a reason why we have a distinction between people and animals guys (though even many animals can live a eudaimonic existence without sex, see neutered dogs).

“sex is criminally overrated” is certainly a statement borne of the sort of careful, even-handed consideration i would expect from someone asserting people aren’t animals
