Eh. Isn't much my '90s sex education class taught that we didn't already know.
Because the classes are too watered down.
I took it in college (sociology credit) in the 80s--and the median score on the anatomy test for the other gender was an F. I also took a class "Marriage and Family Living" (a very good class but even high school is likely a bit premature on this one), one class period was devoted to contraception. We usually had about 200 in the class in a hall that could seat IIRC 465. That day it was totally jammed, there were some people there whose job was to keep shooing people out who were trying to stand in the exit paths (why?! If there was an emergency they would be leaving, not blocking the path! Perhaps it wasn't really about where they were standing but an occupancy limit on the room, though) and people were piled around every doorway several layers deep. This was a 200-level course, I thought the teacher was wasting a class period but the numbers say otherwise.
