Seriously, what is the EDUCATIONAL purpose of this poster? Is it supposed to teach middle-school children something? If so, what? Different sexual activities? Things to experiment with? Broadened sexual license?

Does it really serve any purpose except to titillate susceptible teens? As if that’s necessary with the hormone tsunami they’re already experiencing ...

The only purpose it serves is to attempt to normalize certain acts (such as anal sex) by promoting them as a “typical” way to express your sexual feelings - like cuddling.

"Does it really serve any purpose except to titillate susceptible teens?"

The purpose is to alienate children from any kind of traditional sexual morality, even if most of the described activities are - in certain times and places - consistent with traditional sexual morality. As you say, there is no EDUCATIONAL purpose in the sense of telling students things they don't already know. It is to give the school's imprimatur on the idea of unlimited and irresponsible sexuality.
