As a parent of two children in the Czech school system, I’ve had my fair share of surprises regarding how and what they learn about sex education. When my daughter, then in second grade, brought home her biology book, I wasn’t expecting the detailed anatomical drawings and discussions about sperm, eggs, and reproduction. It all felt quite progressive—more European than my own American upbringing, where sex ed typically involved little more than a condom and a banana, if we were lucky.
