How Sex Got Screwed Up: The Ghosts That Haunt Our Sexual Pleasure is a remarkable achievement: an engaging and readable masterpiece about the history of sexuality. It covers a lot of ground beginning with the Stone Age to Victoria to Our Own Time, exploring sexual myths and laws from sources including anthropology, sociology, and philosophy, to reveal the tyranny of religion and politics. Knowles is a gifted storyteller with the unique ability to bring the reader along on his journey “to better understand what makes us so uncomfortable about sex.”

How Sex Got Screwed Up  

         is a tremendous gift to our sexual health. 

    The book is huge.  .  . . Jon did a fantastic job

of condensing a vast world history into an easy-to-read and succinct outline. I have a lot respect for the way he simplified a story that runs the course of more than 12 millennia . . . . For while it is true that none of us invented sex, it is also true that we did not invent most of our own hassles with it. We inherited most of them.  How Sex Got Screwed Up helps us see this more clearly.
