Susanne has recently had a boyfriend – and has just slept with him for the first time. However, the two teenagers did not use contraception. “The other day I had a headache and took an aspirin,” the 14-year-old would later write in a letter to a German youth magazine. “Fortunately, I didn’t get pregnant. Was it perhaps because of the aspirin? Could you also take headache pills as a contraceptive?”

It’s 1970, pants are flared, and a mustache is all the rage. For a year now, a doctor has been answering questions in the youth magazine under the pseudonym “Dr. Sommer”. Bravo all questions about sex. Questions like those from Susanne. Questions about the first time, about puberty – and about prevention. Because the topic is taboo and there is hardly any information about it.
