I had a really hard time making it through this one.  I can see how this book would be helpful for a lot of people, but I was raised by the internet so I didn't take a whole lot of brand new information from it. A few factoids like "huh, that's neat" but nothing that I feel is going to radically change my life in or out of the bedroom. I also just found the author's writing style somewhat grating and condescending, which is on me, but still definitely impacted my enjoyment of the book overall.
