Sexual education books are hardly necessary anymore: the internet will teach kids everything they need to know, and usually even more (DVDA, look it up!). But the funny thing is that some sex-ed books that were published in the last century can’t have helped any children at all to grow into sexually healthy adults. We know this because we met Jasper Smit recently, a Dutch comedian with one of the biggest collections of sex-ed books in Holland. And because we’re a bunch of rotten dirtbags, we immediately asked him for the nastiest things in his possession. “Most of the books we have are neet and sweet and give you decent advice, like that you shouldn’t have sex with someone if you don’t like the other person”, Jasper said. “But then I also have these books that will make them scared to death of masturbation and fill them with a lifelong repulsion of everything that has to do with sex.” We yelled at him to show us. And he did. Kids, shield your eyes--some stuff's ahead.
