I have read, learnt and practised in my day to day life just two techniques (given below) which are very useful to me in not only controlling the sexual feeling but also to preserve the vital fluid for the benefit of the mind, body and health. The book is a treasure if one is sincere in learning the techniques. The book is full of techniques and every page is useful. I have read plenty of books by different authors on the topic of Sexology and found only one book viz. The Tao of Sexology which contained every information on sex. However this book I feel is equivalent and even more useful than that since it teaches how to learn and practice the techniques, and that too, so many techniques. How to preserve the vital fluid are the two techniques I learnt immediately on purchase of this book. The book is full of techniques and I must devote time to learn the remaining ones. The book is a treasure and I would like to purchase similar books, if available. The book is available at very affordable price and the price is just incomparable with the benefits derived.
