3rd quarter of my 9th grade year was devoted to Sex Ed. I went to Catholic school so it was incorporated in my Freshman Year Growing in Faith Course.

I remember watching The Miracle of Life and seeing a baby born for the first time. A week later, we watched a video of a lady getting an abortion. I know that the videos were meant to scare the shit out of us, and it did its job.

I don't know how much impact it would have on a 10 year old, though.
