First off this book takes a very strong stance right off the bat. Religion is bad for your sex life and your overall mental health. There are some obvious bias leanings. However, he does have evidence to support these statements although he offers little counter evidence to his arguments. He also paints a picture of almost all modern religions but only gives examples primarily, and almost exclusively, from the Abrahamic religions of Judaism, Christianity, and Islam.
I will say I do not agree with all of his statements, but having come from a very religious home I found myself agreeing with most just based on my own personal experience.
I recommend this book to those out there who wonder about what effects being religious may have had on your sex life, especially if you are or were Jewish, Christian, or Muslim. However, do take everything with a grain of salt and weight it against your own experience. It hit home in many places for me, but everybody is different.
I got this because I thought it might be of use to me as a guy and it was. I learned a lot. I'm not sure if audio is the best format for it as the reader may have specific questions and so only need specific sections. Reading what essentially is a report or series of essays (backed up by studies) doesn't exactly translate into a solid audio experience. Given what it is, it did the job very well.
