I recall having it in 5th grade...it was just "oh...these are your testicles, thats your penis, and this is what they do"...

I didn't attend the 6th grade one...

Then there was one in 9th grade where we learned all about STDs (it was a section of our integrated science class, not a one day thing), and we did watch a video that showed a baby coming out...yuck...

Then I came here and in our junior year they threw grades 7 through 12 all in the same room and we watched like 3 videos. The videos were so old, it was basically saying the only 2 ways to get aids were if you a guy screwing other guys, or using IV drugs...hick school AHH.
