Alternated State Orgasms - An altered state orgasm is believed to occur when the brain's level of serotonin is excessively high. The effects of an altered state of consciousness or "near-death experience" have been divided into components and a person may experience all or a combination of these.
People can enter an altered state in many different ways. One example would be through drugs such as LSD, (commonly known as Acid). It is not recommended as method to attain multiple orgasms, however to create the same trance-like state there are often two stages of preparation required. The first phase generally prepares the mind by using such deprivations as water,
food, sleep, sec, or complete inhibition of senses (sight, sound, touch, smell, and taste). deprivation along can trigger hallucinations or an altered sate. People who use shorter term deprivation often induce it through physical injury or flagellation. Today, you can increase your serotonin levels by just taking purchased serotonin in any general health food store to increase the levels without pain or injury.
People often have an orgasm as they approach the altered state, reducing their energy ad serotonin level causing the experience to end. For this reason some have learned to negate the orgasm by physically alternating their penis with stretching or other methods to guarantee an orgasm never occurs . Shamans gave up their sex lives so that the physical orgasm wouldn't interfere with their ability to obtain an altered state.
The catholic mystics used a different discipline to reach an altered state. Religious mystics had to have two striking ingredients present, first their is repression and frustration, a sens of pleasures of the flesh, especially sexual enjoyment, are evil and sinful. Second, there is an apparent form of sublimation and some sexual gratification in the mystical encounter... very few, if any of the prominent mystics led a normal married or sexual life: the mystical life in a sense grow out of perturbation and perversion. it expressed a pathological response to the need for sexual fulfillment by means of a deflected discharge of the libido (The Transcendental temptation, PP 99-100).
There are many cited examples throughout Christianity and the Christian mysticism. an example is the experience of St. Theresa, which she describes it as seeing "an angle close by me, on my left side, in bodily form.. in his hand a long spear of gold, and at Theron's point there seemed to be a little fire. He appeared to me to be thrusting it at times into my hear, and to Perice my very entrails; when he drew it out, he seemed to drown them out also and to leave me all on fire with ta great love of God. the pain was so great that it made me moan; and yet so surprising was the sweetness of this excessive pain that i could not wish to be rid of it. The soul is satisfied now with nothing less than GOD" (mysticism/new York: ORLD/meridian, 1972).
ST. Theresa's sadomasochist bent was evidently a common feature of medieval monastic literature. Auto-sadism and self-flagellation were used by religious mystics, as well as by those simply seeking an altered state of consciousness for sexual pleasure. There were may monks who flagellated themselves with cains, floggers, and whips. Today, one extended arm of the Catholic church Opus Day Monks still use a cilice around the thigh to continually provide pain, thus creating an altered state.
In addition that these types or practices still exist in religion, many people who practice the more "a painful" form of S/M do it to induce this altered sate and view it as a spiritual connection rather than explicitly sexual. Another form of this altered state of transcending is a part of Tantric Sex as well, but without using pain, instead focusing energy from the subconscious and deprivation of senses.
