It's an intriguing idea, one I've never heard before. I'm still digesting it, but I will say that the author makes a compelling case, using Scripture and science to back up his claims. I will say that it fits together well with many other recent attempts to explain why men do what they do. In fact, "Wild at Heart" author John Eldredge has endorsed "Surfing For God."
Lust is a common struggle for most men, and Christians do not get a free pass. I hope this books claims, if true, will lead to freedom for many of its readers.
