When I was 12 years old, growing up in the Netherlands, a woman came to school to give us sex education. She was grey-haired, tough and unsmiling. I recognised the type: my grandmother had taught sex ed at my mother’s school.
We boys and girls sat in the classroom embarrassed. But I also remember wondering: what could this woman teach us? We’d already been taught all about sex at primary school. “I won’t teach you about sex,” she began, “because you know all that. Instead, we’ll talk about relationships.”
Living across the road from me back then was an American teenager called Amy Schalet. Later she returned to the US, and discovered a different world. Many American teens, she noticed with surprise, got pregnant. Some had received scarcely any sex education. Their parents often tried to ban teenage sex, just as American lawmakers try to ban marijuana and prostitution.
