I've done sex-ed as a kid both in Denmark and in the US in the eighties. The danish one was super relaxed. Teacher (female) had lots of good advice like "don't stick anything up there, that you wouldn't put in your mouth". We also had people with different sexualities come out and tell us how that worked. You tried rolling on a condom on replicas. All in all good fun. In the US (liberal school in CA) you were split into boys and girls. Parents had to sign a note that you where allowed to participate. And I don't remember the lessons for being particular informative or relaxed. More like anatomy lessons.
