When I was in high school in the 60’s, my school installed refrigerated vending machines with fresh fruit in them. I didn’t even know what condoms were at that time.
We had pop machines in Junior High and High Schools.
I knew what a condom was by the time I got to Junior High mostly because it was in a lot of 80’s movies.
One time during a school time game one kid, can’t say his name here but I still remember it, decided it was a good idea to take a condom, blow it up like a balloon and toss it in the air. That got the whole school sent to our Homerooms during the game till it was time to go home.
