Title - Why did you call the Method of 3-point Excitation the Method of Resonant Orgasms? Any similarly natural phenomena?
(Revised 12/20/1997, 6/16/1999)

When a woman reaches a sexual orgasm, she experiences a rhythmic contraction of her uterus/vagina at a period of 0.8 seconds per cycle or a frequency rate of 1.25 Hz (Engineering Unit: 1 Hz = 1 cycle per second). Our experiments (recorded in video tapes) show that if the woman rocks back and forth (or down/up-swing) at 0.4 seconds per cycle (2.5 Hz), she experiences eruptive orgasms in 1 minute. Other experiences without video taping also indicate if she is very horny, she can reaches sexual orgasms by rocking a 0.8 seconds per cycle, the same rate of the uterus contractions. Hence, I consider the uterus/vagina is a dynamic (vibration) system (like a suspending bride or piling, for examples), which has a natural frequency of 1.25 Hz (contracting at 0.8 second per cycle). When the stimulating force applying to the woman's trigger zone oscillates at 1.25Hz, 2.5 Hz, 5.0 Hz, and so on, the woman's uterus/vagina will be tuned in to resonate with the simulating force and contract at 1.25 Hz. The uterus/vagina behave like a tuning fork, and her sexual orgasms are like the resonant vibration modes of a dynamic system. Therefore, I term the sexual orgasms produced by this way as the Resonant Orgasms. When the uterus/vagina are tuned in by the stimulating force of 1.25 Hz, I call this phenomena the synthcronous excitation; while the stimulating forces are at the higher frequencies 2.5 Hz, 5.0 Hz, and so on, respectively, I term them as the subharmonic (Trans-Harmonic) excitation. Like a dynamic system, the uterus/vagina have to trap the mechanic (strain) energy done by the pressure(no friction! Friction can produce pain!)against the penis through the trigger zone. When the net accumulated energy (the input pressure energy minus the dissipated energy) reaches or passes over the orgasm threshold, she erupts. The energy accumulating rate depends on the sensitivity of her trigger zone. If she is very horny, the sexual energy is accumulated faster than it is dissipated, even at the rate of the synthcronous excitation. In a routine sexual intercourse, we have to use the subharmonic excitations so that the uterus/vagina can trap the sexual energy faster than it dissipates. The highest frequency a couple can perform is 2.5 Hz (0.4 seconds per cycle). We are unable to swing faster than this speed!

The following graphs show the similar phenomena of energy trapping on a confined, sloping beach of 18 degrees. The experiment was performed in the University of California, Berkeley, for my Ph.D. thesis "Excitation of Edge Waves" during 1978-1981. The sloping beach has a natural frequency of 0.6 Hz for a coastal wave mode called edge wave, and the exciting wave from a wave maker (offshore) is 1.2 Hz. When I started the wave maker at the tuning frequency the edge wave was excited immediately, reaching a maximum very quickly (breaking),in less than 1 minute, and repeating a growth-breaking process over and over again. Here, the uterus/vagina are like the confined, sloping beach, that traps the sexual energy into the Epicenter; the sexual orgasms are like the edge wave, and occur again and again as long as the exciting force keeps going! She can have as many orgasms as she wants by this method. However, 20-cycle orgasms will exhaust her. Some women may be able to withstand up to 30 cycles. You call it "Achieving Multiple Orgasms" but I term it "Tuning Multiple Orgasms." Please remember that to make her come it requires 100-300 continuous (non-stop) love thrusts with a hard penis.

NOTE: I have included Five (5) samples of the vocal(moan and cry) responses to multiple, sexual orgasms and Four (4) motion pictures with sound of the actural multi-orgasm intercourses in the CD-ROM Version of this book, so that you can understand what do the multiple (up to 20-cycle), sexual orgasms sound and look like. You will see the transient responses of the woman's face and voice to the multi-orgasmic excitation. You will also hear the synchronous or trans-harmonic breathing, that tells men how to use the Sexual ChiKong breathing for prolonging intercourse and women how to use the sexual ChiKong breathing to synchronously contract her vagina muscle for the excitation of multiple orgasms.

Engineering Point of View:

All the vibration/oscillating phenomena in the field of engineering are similar to our human bodies - male or female. This is not coincident, but universal! Just follow the rule of the nature,I call it Tao, a loving couple will enjoy their sexual orgasms as one of the natural phenomena.
