Well, I was sort of thinking of drugs when I made the analogy, but the government policy response is similar (i.e. the government wants to reach into my wallet to subsidize free syringes, drug purity tests, etc.)
> Sex is something hardwired into people
This is an appeal to nature. We naturally want to do it, therefore we shouldn't try to resist it? There are many counter examples: violence, incest, tribalism, and other undesirable evolutionary behaviors are hardwired into people (and animals) too, yet our efforts to reduce/temper their influence and emergence can be quite effective (though not 100% effective). Why is sex any different? I think we could temper sexual activity with the right messaging (and more importantly, leading by example) to youth.
Something like "sex is something that should be reserved for a committed relationship, not a recreational activity you should do casually - the latter leads to a lot of problems in society. Nevertheless, the choice is up to you and here are the risks and things you need to know either way..." Obviously "accidents" would still happen, but the idea would be to address the root cause of sex-related issues in society instead of throwing your hands into the air and deciding to just treat the symptoms.
