What this book is about
- First published in 2001, Willies: A User’s Guide (ZEP) quickly became known for its funny, playful approach to puberty and sex education.
- The book covers physical changes during puberty, being in love, kissing, dating, making love, making babies, and protecting yourself.
- Remarkably, it even discusses pornography – including online porn – long before it became a mainstream concern for parents and educators.
- The humour runs throughout, with cheeky illustrations and interactive features. One memorable page has readers stick a finger into a hole to mimic how a penis goes into a vagina – something many kids will find hilarious (and which can break the ice for tricky conversations).
- While it’s funny, it’s not shallow – the book also emphasises relationships, love, and respect, showing that sex isn’t just about bodies but also about feelings and connection.
- Inclusive of same-sex relationships, it avoids assuming that boys will only fall in love with girls, which was ahead of its time for a book published in the early 2000s.
- Parents may find some sections dated, but this creates an opportunity to talk with kids about how things have changed since the book was written.
- A great choice for kids who resist “serious” puberty books, or for parents who want to use humour as a way into conversations about growing up, relationships, and sex.
