I'm glad that, for the moment at least, sex ed has mostly advanced over the days of the film strip and a pamphlet. At least in many places. (I have to admit that in my private, religious high school, we didn't even have that.) I did get a pamphlet from the doctor once entitled What is Happening to my Body? It had cheesy pink flowers on the cover.
Still, there is a good deal of camp value in those old scare films.
I also have fond memories of the sex-ed scene in Monty Python's Meaning of Life, a movie which also featured that delightful ditty, "Every Sperm is Sacred".
(Ok, I'm getting a little past fully coherent, but I am still able to look up which titles should be italicized, and which need brackets. Go me.)
