Sex education

I honestly feel like sexual education classes should be mandatory in high school 🤦🏻 there are so many teens/ people who don’t even know that start of it. For instance, I’m 20, just lost my virginity a few months ago and just barely learning how sex works. I’m glad I did so much research before hand. How pre cum can hold sperm or condoms aren’t 💯 effective. I also think classes should be held about the body like how to tell changes as one grows, to better understand the anatomy of ones own body. I can’t tell you how many times I’ve had to google things I had no clue on and then worry crazy because what if. It’s a scary thing not knowing. I’m not sure if other schools have it but I know my high school didn’t. Thoughts?
