Gentlemen: Do you want to know how to (1) Stop Premature Ejaculation (2) Solve the Erection Problem, (3) Prolong your intercourse, (4) Stay harder and longer, or (5) Take good love positions and effective actions to make her comes many times in one night?

Or, Ladies and Gentlemen: Do you want to restore or maintain your sexual potential and health for a sizzling sex life?

This book was compiled, based upon my 20-year experiemental study on intercourse, sexual techniques, and methods of restoring sexual potential and health.
This study included:
(1). Signal processing of vocal responses to different sexual orgasms (3 types - one on the clitoris and two inside the vagina),
(2). The effects of the stimulation pressure and rate (speed) on THE women's orgasms,
(3). The effects of love positions and actions(thrusting direction and speed, attack angle, stimulation spots) on the timing of women's orgasm and men's ejaculation,
(4). Application of the abdomen (belly) breathing to the control of men's ejaculation and the acceleration of women's orgasm,
(5). Developing special methods to power up the penis which becomes extremely hard and stay longer(up to 90 minutes in my own record), for more than two sequences of multiple, sexual orgasms, so that the man can use one stone to shoot more than one bird,
(6). Testing of Vacuum-cupping and Pressure Massages, foods and herbs for retaining and reactivating (restoring) men and women's sexual potential and energy ( In Fact, Vacuum-cupping Massage also solves all my pain (back) and numb (legs and hands) problems. This is the most powerful therapy to restore my youth body.)
This book contains more than 100 illustrations (pictures, graphs, love positions and actions) to instruct you how to do it, not only for your sexual pleasure, but also for your health - present and future. In addition, the CD-ROM Version contains 9 motion pictures (AVI files) pluse 5 samples of vocal responses to trans-harmonic and synchronic excitation of multiple sexual orgasms.
