Many miserable people married young and are trapped until they die.

And countless couples followed this path in life and are not happy at all, and countless individuals can't for a variety of reasons follow this path. But public health advice should also be available to them.

Psychology is a whole other matter, but if you're talking about sleeping around like Bonnie Blue then it is a form of Russian roulette and is likely to result in physical health trouble. Especially if people are having unprotected sex.

HPV spreads through oral sex as well by the way.

I am not talking about 'sleeping around' at all. Just by the look at the divorce rates around the world it is very clear that 'marry young and then never change partners' is an advice divorced from reality.

Divorce is horrible for sure but that is mainly down to interpersonal relationships.

It is a simple fact that unprotected sex with large numbers of people is very risky. We should have learnt that lesson in the eighties.

If there's somebody out there advocating for "unprotected sex with large numbers of people", you should go post at them, because I don't see that here.

The biggest barrier to disease transmission reduction, at least here in the US, is uncritical abstinence promoters like yourself. It works, at best, for a small fraction of the population, and leaves the rest woefully unprepared for the biological realities. The best solution to STDs is education. Which, yes, should emphasize that not having sex is an option, but cannot stop there.

Same goes for people who did not.
