From being around plenty of childeren. Some of them can start doing it at a very young age just because it feels nice, not from seeing it or understanding it, just from being human and having genitals.

This is an anecdote, i might as well reply with my own anecdote of not seeing such behaviour, both carry as much weight. If one is to base education of children on this notion, there needs to be a study to prove it.

But wouldn’t it be nice if the fate of a child would have more then one support system? Like if the parents are bad maybe the school system can help the child…

Yes and thats the whole point of this post, to criticise the bourgeois education system. Seems to me that you’ve interpreted my critique of the bourgeois education system as demanding there to be no sex education to begin with. Of course there needs to be sex education, but based on materialism and collectivism, ie. marxism. Just look at socialist states for inspiration, like the DPRK. “Sex education” in the imperialist West is based on an individualist ideal of sex only existing for pleasure, with procreation merely as an option, when a marxist recognizes the primary function of sex as procreation, with pleasure merely existing to encourage this. There are then other conclusions that are drawn from whichever view one has, mainly having to do with relationships.
