Query: Penis, Male Pelvis and Pubic Area: Explored in Depth

The author has written an intelligent, frank and provoking book about the area of the body least talked about in an intelligent, frank and provoking manner. I consider this book essential for anyone in the "body work" field. It is a well written authoritive work by a scientist well versed in anatomy, physiology, and somatics. An excellent and important book for any Medical Doctor, Psychologist or Physical Therapist yet easily understood and enjoyed by someone with a less scientific mind. In fact, I consider this book a "MUST READ" for P.T.'s, Massage Therapists, and all body workers, consultants and trainers who work with men. I would also consider this book an excellent primer for any one (woman OR man) involved in a sexual, romantic, or loving relationship with a male. It is the equivalent of the famous "Our Bodies Our Selves" only about men. I recommend this book with highest praises!
