It’s not as bad as people make it out to be.
But it helps to have a laid back teacher.
My school gradually told us about sex-related topics.
Example: One year, they separated the girls and boys, and each group talked about puberty. Next year, they talked about sexually transmitted diseases. The next year we learned about the opposite gender, sex in general, and how a new human-being is formed.
