For example, I once started reading a novel by Judy Blum. Yes, the same Judy Blum who wrote all those cute childrens books. It was touted to be a young adult novel, so as a writer of young adult novels, and the book having been written by a famous author like Judy Blum, I thought it would be a good read. About a quarter of the way through it, I had to take it back to the library. I could not read it any further. It was filled with graphic sex, describing the act in great detail. I suppose it was supposed to have some kind of lesson about a girl losing her virginity and the consequences that follow, but to me it was nothing more than child pornography. It made me sick to think our children are reading that kind of filth.
I don't have a problem with an author writing about sex, even events leading up to a sexual encounter, but to describe the act in detail is pornography in my mind.
I like an edgy book now and then, if it's done without appealing to our children's baser and prurient interests. And I could go off on another tangent and say edgy does NOT need to have the infamous "F" word, or many of its synonyms. But that is something for another discussion.
