When Boys and Girls Become Men and Women by Jorg Muller and Dagmar Geisler

Book Review

A short overview of this book

When Boys and Girls Become Men and Women by Jorg Muller and Dagmar Geisler is a German puberty and sex education book that is straightforward and refreshingly direct.

I have a soft spot for European books as they take a very matter-of-fact approach to explaining sex and growing up.

This book is very comprehensive and discusses a lot of different topics, including:

  • What Girls Want to Know About Boys
  • What Boys Want to Know About Girls
  • Girls and Boys Grow Up
  • Good Personal Hygiene
  • Love—and What It Entails
  • What Happens During Sexual Intercourse
  • Sex, Pregnancy, and Contraception
  • Even Healthy People Should Go to the Doctor
  • Pregnancy—From a Cell to a Whole Person
  • A Baby Enters the World

I guess you could liken this to be a European version of the big Robie Harris sex education books.

You can learn more on this page, about how to talk to kids about sex education.
