Many Taoist practitioners link the loss of ejaculatory fluids to the loss of vital life force: where excessive fluid loss results in premature aging, disease, and general fatigue. While some Taoists contend that one should never ejaculate, others provide a specific formula to determine the maximum amount of regular ejaculations in order to maintain health.[4] The general idea is to limit the loss of fluids as much as possible to the level of your desired practice. As these sexual practices were passed down over the centuries, some practitioners have given less importance to the limiting of ejaculation. Nevertheless, the "retention of the semen" is one of the foundational tenets of Taoist sexual practice.[5]
There are different methods to control ejaculation prescribed by the Taoists. In order to avoid ejaculation, the man could do one of two things. He could pull out immediately before orgasm, a method which Joseph Needham termed "coitus conservatus".[6] The second method involved the man applying pressure on perineum, thus retaining the sperm. While, if done incorrectly can cause a retrograde ejaculation, the Taoists believed that the jing traveled up into the head and "nourished the brain."[7] This method is referred to by some Taoist scholars as "The Million Dollar Point" (reference Mantak Chia), regarding it as either a cheap lesson for income or a backup method, believing that it somehow lessened the loss of "jing" from a full ejaculation. Some modern teachers have come to the conclusion that the method should not be used because of potential dangers.[8] Another method involves the Taoist to train himself to separate the impulses of ejaculation and orgasmic contraction (the contraction of the pelvic muscles that "pump" the prostate and the ejaculate). By separating these impulses, at the point of orgasm, the man can halt penetration but remain inside his partner, and forcibly clench his pelvic floor ("stunting" the initial prostate contractions), while simultaneously adopting a meditation like "intention" that these Taoists believe redirect not the physical sperm, but the life energy (jing) it contains up the back and to the center of the brain. This way the man will still have an orgasm, but will not ejaculate, and most importantly will not lose his erection. This formula prescribes the man to climb a "ladder" of escalating orgasms in conjunction with the meditation like "intention", in order to cultivate and store massive amounts of "jing". If performed successfully the male should have no stagnating pain in the testes, and should have no semen in his urine, as well as the health benefits expected by practitioners [1]. Those that practice this method believe that it is one of the keys to immortality.
