I was reading the book The Great Tao by Stephen Chang, and he talk about a sexual technique where the man, right before ejaculation, presses on an acupuncture point between the legs so that the ejaculation doesn't occur because the semen is blocked. It is supposedly a good practice because you don't lose all the energy you normally would. Is this a safe practice? It sounds like a good thing, since you won't lose all that energy and you can still have sex. Does anyone know about this?
