Despite what you may think from the title, this book is not porn. Bonk is a non-fiction book about the history and stigma of sex research. This book is about as non-sexy as you can get. This book made me so squeamish that I frequently had to turn it off and scream. I listened to this as an Audiobook, and a couple of times, I almost drove my car off the road.
Mary Roach is nothing if not detailed. This book is extensively researched. She writes about the research of Masters and Johnson and Alfred Kinsey in the 1950s. She writes about modern day sex researchers and even has sex with her husband in an MRI. There are chapters on male orgasm, female orgasm, masturbation, and anything else you can think of. The most disturbing section was about Victorian attitudes towards sexuality. Little boys had to wear a contraption at night that ensure that if they had a nocturnal erection, they would be in pain. Thankfully, we have come a long way since then.
This book was fascinating and educational, however this is not a book I would recommend for someone with a weak stomach. Some sections are fairly graphic and disturbing.
