Well, I don’t have to do it for my own children yet.
But since I’m a Science teacher, I need to teach sexual reproduction of plants and humans to fifth graders. So, 11-year-olds in my country learn the names of various private parts of the human body, as well as the fertilisation process. Boys and girls attend the lesson conducted by their Science teacher together.
As for the more emotional aspects of baby-making, these 11-year-olds also attend Family Education lessons. They are split into different classes - the boys taught by a male teacher and their female classmates taught by a lady teacher. You betcha some of these discussions can get quite probing and intense!
We advocate abstinence before marriage btw. No mention of safe sex. Zilch!
