Yumi Stynes’ children’s sex book tops Amazon bestseller list as critics slam book for being too graphic: ‘let boys be boys’
- ‘Graphic’ Sex Book for Teens Hits Number One on Amazon
- Yumi Stynes’s Welcome to Sex book has been criticized
- His illustrations show masturbation and oral sex positions.
A children’s sex book that goes into detail about graphic sexual acts—and consent—has hit number one on Amazon’s bestseller list, even as it attracts mostly one-star reviews.
Host Yumi Stynes’ book Welcome to Sex has rocketed to number one on Amazon Australia amid controversy over its graphic caricatures, including a depiction of ‘scissors’.
It comes after Dymocks and Big W received criticism for selling it in their children’s section both online and in stores.
The book, which has been promoted on Amazon as an “age-appropriate introductory guide to sex and sexuality,” was written by Stynes and teen magazine advice columnist Dr. Melissa Kang.
Amazon reviewers criticized the book even though it peaked at number one for displaying too much information for young minds.

Yumi Stynes (pictured outside her Balmain apartment on Thursday) has said she is “really proud” of her book.
The post details consent, LGBTQI issues, masturbation and gender curiosity, and some adult concepts.
Amazon recommended the book for teens ages 14 and up and retails for $19.25.
But Ms Stynes has said that “a mature eight-year-old could just flip through it”.
Several reviewers criticized the book.
‘Since when was sexuality and sexual content pushed so hard against children until now? Kids be kids,” wrote one reviewer who gave it a 1-star rating.
“I’d give it a 0 if I could,” said another. “I found this book disgusting and totally unacceptable for children under the age of consent, which in Australia is 16.”
Another reviewer said, “Very quickly it moves on to topics that most would find wildly inappropriate for a kid just learning about periods, crushes, feelings, and sex.”
‘The great parts of this book are dwarfed by the explicit and inappropriate parts and the ill-chosen age recommendation.’

Some have criticized critics saying the book can keep children safe from sexual predators (a page from the book is pictured)
But another reader said the “factual and easy to read” book gave children insights into sex and bodies.
Stynes has said that she is “very proud” of the book.
It’s a book, people. If you don’t want to read it, by all means, don’t read it,’ the radio host and ABC host said Thursday.
“If you don’t want your kids to read it, you REALLY don’t have to buy it for them,” he wrote on social media.
But when asked to speak about the post on Thursday, Ms Stynes scoffed at the approach, issuing a warning: “Don’t ever come around here again.”
