I did this in a men's group at church. I think it had some good intentions, but in some cases, I think it had the opposite effect on me.  It talked about things that "most men struggle with" but I think it was more from their own experiences... because certain examples I didn't struggle with... until I went through this book.  As one Amazon reviewer put it... he spends over half the book making us feel bad for sexual sin, when most of us know it's a problem and want practical solutions to solving it. And while his ideas aren't bad, they don't necessarily seem practical if we want to engage in everyday life.
