Is it wrong that I didn't actually know where babies come from women until I was 22?

Sexual education is lacking in some schools but important things like how life happens is important enough that you should do your research. After all you don't want an unexpected child because you didn't know how things work.
It's not your body so how would you know?
You shouldn't be ignorant about sexual education. There's plenty of resources online to help you if you need to fill in gaps in your learning from school. It will complicate your relationships and may harm them if you don't know the basics at your age.
