My wife was a teacher and sexual health educator for most of her career (grades 8-12).

When I was getting sex ed, part of the teacher's responsibility was grounding us in basic facts to dispel word-of-mouth myths that were patently absurd to anyone with any experience (like "sneezing after sex prevents pregnancy").

My wife's tasks was to explain that the hardcore porn they'd all seen was unrealistic in the same way that action movies completely misrepresent fights and stunts, and the real world doesn't work that way. Her problem was that she was arguing with video evidence that it could. The kids aren't unhinged, but they're definitely misled in a completely different way than we were.
