This thick book feels very dated when you read it, as if it had been written in 1980.
It presents a huge amount of information on the historical Taoist / Chinese points of view on human sexuality, and could be said to give a fairly comprehensive view of the most basic elements of the subject. Personally, I found it to not be useful except as a reference book, and felt it would have benefited from a more aggressive editor.
It is packed with information - more than forty-seven diagram and charts of reflexology and acupressure / acupuncture points. Unfortunately most of this information is not of much practical use. It is also full of misinformation - a man's `jade stalk' does not have to be a particular shape to gratify a woman, and the author would appear to believe that women only achieve sexual gratification through sexual intercourse. It contains the usual long, overly detailed explanation of why it bad for men to ejaculate, and the obligatory chapter (eight pages) on thrusting patterns - complete with detailed charts. Like many Chinese books it appears to have been researched and written by a man, and a fair amount of information about women appears suspect to me (I'm a male) - I do not believe it is likely that a jade stalk, however long, would ever enter the cervix. (obviously you do not want to go in the cervix)
As far as sexual energetic techniques, the deer technique is as far as the book goes. It is described very well. That's it. I would say this book has fewer relevant bedroom qigong techniques than any other I've read.
The text describes eight very simple general chi kung exercises in detail, and mentions but does not describe the crane and tortoise breathing exercises.
To give you an idea of the level of detail:
- a one page table of Chinese sexual euphemisms - "jade flute", "clouds & rain"
- eight pages of rules for a Taoist sex act [not: when you are tired, after eating, during menstruation, during intense storms, after flying in an airplane, etc.]
- Erotic massage (10 pages) - primary, secondary and tertiary erogenous zones of the male & female body, relevant acupuncture points of the hands and feet, the twelve reflex zones of the jade stalk(male) and jade gate (female), reflexology points of the labia ...
- determining biological age from the angle of the erection (4 pages)
- Techniques to "improve" the shape of the `jade stalk'
There is a huge overlap between the material in this book and the material in Stephan Chang's Tao of Sexology. One would guess they studied with the same teacher.
I would not recommend this book, except as a reference.
