Sex education is the term used to talk about how babies are made and how our bodies work. It helps us understand how boys and girls are different, and how they grow and change as they get older. It's important to learn about our bodies, but we should only talk about sex education with grown-ups we trust, like parents or teachers. It's important to remember that sex education is a topic that is better understood when you are a bit older, like when you are between the ages of 10 and 12.
