Query: Insightful Analogy and Great Book!

I generally don't to gravitate to books about the world of business -- I'm one of the "disillusioned" ones. And, I don't usually buy books with the word sex in the title either! But this book.....WOW! The metaphor (intimate relationships-business relationships) is very well-developed and makes for a very understandable, easy, and humorous read! As I read it, I found myself readily applying what I was learning to both business and personal relationships! I definitely recommend this fresh, new, approach to solving some of the many problems plaguing personal and businesss relationships these days!
