I assume they're trying to out-do the old Soviet joke.

Preface to a new sex education schoolbook:
"Dear children. There are three kinds of love. First, there is the love between parents and children. We're sure all of you are already familiar with that, so there is no need to discuss it here. Second, there is the love between two adults. Some suggest it might be too early to tell you anything about that yet. And third, there's the love the People feel toward the Party, and that is what we shall discuss for the rest of this book..."

Religious indoctrination and shaming.

Essentially "Don't do it if you don't want to catch a disease, get pregnant, or get someone else pregnant. Only way to be absolutely sure."

Which is true, to be fair. I mean a majority of students aren't going to implement that and it's missing 99% of what you should probably know, but what little is left isn't wrong as such.
