@Silence04 I was one of those shy kids who got embarrassed easily. I would never have asked.
I was grateful that my parents had books that were conveniently left around the house, and we started our formal sex ed classes in 6th grade, then had another in 8th grade which was much more specific, and even more in 10th grade. In 6th grade we learned about how our bodies worked (periods and fallopian tubes and all that stuff), but it was never mentioned how the sperm actually got inside the woman’s body to fertilize the egg to make a baby. That was revealed to us on the school yard. By 8th grade, that was all sorted out correctly. It should have been sorted out in the first class in 6th grade. No mention was made of birth control until 10th grade, but our health teacher, a very cool male teacher, showed us how to put a condom on a banana, so that we could see how it was done properly, rather than just saying, “Hey kids, use a condom!” None of my friends or I had sex while we were still in high school. I’m sure there were some kids who did, but I think it helped that we were very informed about the risks, as well as how to properly use birth control.
Back then, most girls started their periods when they were 12 or older, so it worked out reasonably well, and I’d never heard of any girl having sex ed (or health and hygiene as they called it) at that time, but this was in the mid 70’s.
I remember one girl got pregnant by her boyfriend in 9th grade and it was a huge scandal. Another girl, also in 9th grade got pregnant by one of the teachers. Yikes!
