Query: Disappointing

I bought the 4 DVD collection thinking there would be more to learn from viewing all 4. Not so. There seemed to be little difference in the methodologies applied, and those seemed very limited. I doubt that any of these DVDs will ever be put on my player again. A far better source of information (and far better dollar value) is the book (available from Amazon) "She Comes First (the thinking man's guide to pleasuring a woman)" by Ian Kerner, Ph.D. The anatomical information is more detailed, explains far more about just what is going on down there, and how to get the desired results. These DVDs added nothing.
