Involuntary Contractions Without Aneros. Now what?

Does anyone have any advice about how to guide these sensations, and perhaps channel the random leg shaking into something else? Well it sounds like you've fully awakened your prostate and now it is ready to enliven your every waking moment with erotic energy coursing through your body. This is a good thing, it has the potential to enrich every aspect of your life, not just your sexual functioning. At first this continual body energy flow may seem confusing or even disturbing, but know this, it will lessen in time. You will accept this as part of your everyday existence and quietly enjoy the pleasure of knowing what is on tap for you when you wish to enjoy it more fully.

Obviously while masturbating you are deliberately intending to open the channels of erotic energy for the pleasure to flow. If you think of your muscles as conduits for some of that energy then the shaking is the result of a lot of energy passing through small channels causing vibrations as the energy tries to rapidly flow through, not unlike small pipes trying to handle large volumes of fluids. Learning to relax your muscles at these times is like expanding the diameter of the pipes, lowering the pressure, allowing the flow rate to decrease and easily handling the volume of fluid (energy), the shaking stops. This allows the energy to flow freely, then you may be able to use your mind's intent to direct some of this energy to other parts of your body for healing or pleasure purposes.
Good Vibes to You !
