Have a look at this book "welcome to sex" that is aimed at tweens....
Supposedly it's classed as sex education but some of the advice such as "if you're going to send nude pics, just crop your head out" is totally inappropriate and child grooming. 1 of the authors even says a the book is appropriate for a mature 8 year old. A petition for signing to get it off the shelves.
