question: Why does our brain immediately change our thinking after we orgasm?
comment: Hormones! Our mood can greatly change based on the chemicals in our brains (like from certain drugs). When men orgasm, most of them become disinterested in sex for a time (that time varies from person to person) and mr happy takes a nap (again this time will vary) but it happens because we release hormones.
passages: There have been very few studies correlating orgasm and brain activity in real time. One study examined 12 healthy women using a positron emission tomography (PET) scanner while they were being stimulated by their partners. Brain changes were observed and compared between states of rest, sexual stimulation, faked orgasm, and actual orgasm. Differences were reported in the brains of men and women during stimulation. However, changes in brain activity were observed in both sexes in which the brain regions associated with behavioral control, fear and anxiety shut down. Regarding these changes, Gert Holstege said in an interview with "The Times", "What this means is that deactivation, letting go of all fear and anxiety, might be the most important thing, even necessary, to have an orgasm."

   The phenomenon is first mentioned by the Greek doctor Galen, who wrote that "Every animal is sad after coitus except the human female and the rooster." The philosopher Baruch Spinoza, in his "Tractatus de Intellectus Emendatione", wrote: "For as far as sensual pleasure is concerned, the mind is so caught up in it, as if at peace in a [true] good, that it is quite prevented from thinking of anything else. But after the enjoyment of sensual pleasure is passed, the greatest sadness follows. If this does not completely engross, still it thoroughly confuses and dulls the mind." 
   An increased infusion of the hormone oxytocin during ejaculation is believed to be chiefly responsible for the refractory period, and the amount by which oxytocin is increased may affect the length of each refractory period. A scientific study to successfully document natural, fully ejaculatory, multiple orgasms in an adult man was conducted at Rutgers University in 1995. During the study, six fully ejaculatory orgasms were experienced in 36 minutes, with no apparent refractory period.

   Section::::How the ritual ends.
  
  The rite may end in one of two ways. The ritualist may simply sink into total sleep, or he or she may achieve orgasm and then sink into a deep and "undisturbable" sleep. Jason Newcomb, however, concludes that sexual exhaustion achieved through repeated orgasm may also lead to the ritualistic state and does not necessarily end the rite. Frater U. D., however, has argued that the orgasmic moment should not be lost and that the individual should strive to use the moment for spiritual or magical purposes.
   Ellis also argues that auto-erotic impulses can be heightened by bodily processes like menstrual flow. During this time, he says, women, who would otherwise not feel a strong propensity for auto-eroticism, increase their masturbation patterns. This trend is absent, however, in women without a conscious acceptance of their sexual feelings and in a small percentage of women suffering from a sexual or general ailment which result in a significant amount of “sexual anesthesia.”

  Masters and Johnson described the two-stage detumescence of the penis: In the first stage, the penis decreases from its erect state to about 50 percent larger than its flaccid state. This occurs during the refractory period. In the second stage (and after the refractory period is finished), the penis decreases in size and returns to being flaccid. It is generally impossible for men to achieve orgasm during the refractory period. Masters and Johnson argue that this period must end before men can become aroused again.
  
  Section::::Resolution phase.:Resolution in females.
   The observation that women tend to reach orgasm more easily when they are ovulating also suggests that it is tied to increasing fertility. Evolutionary biologist Robin Baker argues in "Sperm Wars" that occurrence and timing of orgasms are all a part of the female body's unconscious strategy to collect and retain sperm from more evolutionarily fit men. An orgasm during intercourse functions as a bypass button to a woman's natural cervical filter against sperm and pathogens. An orgasm before functions to strengthen the filter.
   Masters and Johnson were some of the first researchers to study the sexual response cycle in the early 1960s, based on the observation of 382 women and 312 men. They described a cycle that begins with excitement as blood rushes into the genitals, then reaches a plateau during which they are fully aroused, which leads to orgasm, and finally resolution, in which the blood leaves the genitals.
   Ellis says the film was based on a personal experience. "Twice in my life I've had girls ask me to oblige them in that way. And both times I've said yes. And both times they failed to turn up and go through with it. The frustrating stop-star love-making Geoff and Maureen indulge in as they go about graphing his sperm count and her temperature to maximise their chances of conceiving is also something I've been through. When Anne and I were trying to have our third child she'd kick me awake at four in the morning saying her temperature was up and I'd have to reorganise my protoplasm to suit the occasion."
   Masters and Johnson argued that, in the first stage, "accessory organs contract and the male can feel the ejaculation coming; two to three seconds later the ejaculation occurs, which the man cannot constrain, delay, or in any way control" and that, in the second stage, "the male feels pleasurable contractions during ejaculation, reporting greater pleasure tied to a greater volume of ejaculate". They reported that, unlike females, "for the man the resolution phase includes a superimposed refractory period" and added that "many males below the age of 30, but relatively few thereafter, have the ability to ejaculate frequently and are subject to only very short refractory periods during the resolution phase". Masters and Johnson equated male orgasm and ejaculation and maintained the necessity for a refractory period between orgasms.
   All such activities appeared to Freud to contradict the organism's search for pleasure, and therefore 'to justify the hypothesis of a compulsion to repeat—something that seems more primitive, more elementary, more instinctual than the pleasure principle which it over-rides': 'a daemonic current/trait', 'a daemonic character', a 'daemonic compulsion', likely alluding to the Latin motto "errare humanum est, perseverare autem diabolicum" ("to err is human, to persist [in committing such errors] is of the devil"). Following this line of thought, he would come to stress that "'an instinct is an urge inherent in organic life to restore an earlier state of things"'; and so to arrive eventually at his concept of the death drive.
   After orgasm and ejaculation, men usually experience a refractory period characterised by loss of erection, a subsidence in any sex flush, less interest in sex, and a feeling of relaxation that can be attributed to the neurohormones oxytocin and prolactin. The intensity and duration of the refractory period can be very short in a highly aroused young man in what he sees as a highly arousing situation, perhaps without even a noticeable loss of erection. It can be as long as a few hours or days in mid-life and older men.

  Researchers have used the PRP paradigm design to study various topics in psychology, and various results indicate how these areas of psychology are negatively affected by the psychological refractory period delay.
  
  Section::::Results.:Personality and intelligence.
  
  PRP is not dependent on "personality". Upon experimentation, participants were tested with a PRP paradigm in which the first task was an auditory task and the second task was a visual two choice task. Results indicated that there is an overall decrease in reaction time, exhibiting a psychological refractory period effect, however, there was no effect due to varying levels of extroversion and introversion.

   Human brain wave patterns show distinct changes during orgasm, which indicate the importance of the limbic system in the orgasmic response. Male and female brains demonstrate similar changes during orgasm, with brain activity scans showing a temporary decrease in the metabolic activity of large parts of the cerebral cortex with normal or increased metabolic activity in the limbic areas of the brain.
   In the Bene Gesserit ritual known as the spice agony, an acolyte ingests an "illuminating poison" called the Water of Life which, if the initiate survives the ordeal, unlocks these Other Memories. These ego-personalities reside in the background of consciousness, but may be accessed to provide unique knowledge and insight. However, the memories unleashed in this ritual are always of female ancestors; access to the male line is unique to the pre-born, and theoretically to a specially-bred male known as the Kwisatz Haderach.
   Specifically in relation to simultaneous orgasm and similar practices, many sexologists claim that the problem of premature ejaculation is closely related to the idea encouraged by a scientific approach in the early 20th century when mutual orgasm was overly emphasized as an objective and a sign of true sexual satisfaction in intimate relationships.
   A usual precursor to ejaculation is the sexual arousal of the male, leading to the erection of the penis, though not every arousal nor erection leads to ejaculation. Penile sexual stimulation during masturbation or vaginal, anal, oral, or non-penetrative sexual activity may provide the necessary stimulus for a man to achieve orgasm and ejaculation. With regard to intravaginal ejaculation latency time, men typically reach orgasm 5–7 minutes after the start of penile-vaginal intercourse, taking into account their desires and those of their partners, but 10 minutes is also a common intravaginal ejaculation latency time. A prolonged stimulation either through foreplay (kissing, petting and direct stimulation of erogenous zones before penetration during intercourse) or stroking (during masturbation) leads to an adequate amount of arousal and production of pre-ejaculatory fluid. While the presence of sperm in pre-ejaculatory fluid is thought to be rare, sperm from an earlier ejaculation, still present in the urethra, may be picked up by pre-ejaculatory fluid. In addition, infectious agents (including HIV) can often be present in pre-ejaculate.
   To treat premature ejaculation, Masters and Johnson developed the "squeeze technique", based on the Semans technique developed by Dr. James Semans in 1956. Men were instructed to pay close attention to their arousal pattern and learn to recognize how they felt shortly before their "point of no return", the moment ejaculation felt imminent and inevitable. Sensing it, they were to signal their partner, who squeezed the head of the penis between thumb and index finger, suppressing the ejaculatory reflex and allowing the man to last longer. 
   On the same note, it may be the visual factor present in masturbation that may delay vaginal ejaculation. As the sensation during masturbation is intrinsically linked with the visual input of a sexual model, be it male or female, the diminished view during sex may result in the loss of that link, and as such, delay ejaculation in the man. A possible cure for this may be a better view of the partner during intercourse.

   In addition to physical stimulation, orgasm can be achieved from psychological arousal alone, such as during dreaming (nocturnal emission for males or females) or by forced orgasm. Orgasm by psychological stimulation alone was first reported among people who had spinal cord injury. Although sexual function and sexuality after spinal cord injury is very often impacted, this injury does not deprive one of sexual feelings such as sexual arousal and erotic desires.
  
  A person may also experience an involuntary orgasm, such as in the case of rape or other sexual assault.
   The traditional view of male orgasm is that there are two stages: emission following orgasm, almost instantly followed by a refractory period. The refractory period is the recovery phase after orgasm during which it is physiologically impossible for a man to have additional orgasms. In 1966, Masters and Johnson published pivotal research about the phases of sexual stimulation. Their work included women and men, and, unlike Alfred Kinsey in 1948 and 1953, tried to determine the physiological stages before and after orgasm.
   Joe Griffin discovered, from years of research on his own dreams and those of others, that dreams are metaphorical enactments of emotional arousals that were not expressed or acted out during the day. This is nature’s evolutionary solution to animals’ need to inhibit arousals, such as anger, urge to eat or urge to mate, whenever such instincts are inappropriate or dangerous to act on at the time; the arousals are safely deactivated later in dreams. In civilised societies, of course, people are commonly in circumstances where strong feelings are aroused but it is inappropriate to act on them. Arguments do not feature in dreams, as the emotion is expressed; private worries, fears, urges not given into (such as for a forbidden food or activity) do. Griffin has theorised that by enabling arousals to be safely discharged in dreams, once they have been activated, REM sleep serves to keep our instincts and drives intact. (If continually activated but not acted upon in any form, they would gradually become extinct.) The PGO spike activity prior to and during dreaming signals that there is material to be acted out and discharged. Once the instinct patterns have been deactivated, the data processing potential of the neocortex is released, ready to deal with the emotionally arousing contingencies of the following day. Far from dreams being the cesspit of the unconscious, as Freud proclaimed, Griffin says that they are the equivalent of the flushed toilet.
   Harp and Mayer conducted an experiment using a lesson about lightning strikes. The effect of lightning strikes on airplanes was added as a seductive detail. In six out of six experiments, learners who studied the base lesson without the seductive details about the strikes on airplanes demonstrated they were three times more likely to recall the structurally important details. They also performed much better on a problem-solving task than learners whose lessons included the seductive details. Harper and Mayer suggested seductive details do their damage when learners are consolidating and organizing new information by forming knowledge structures ill-suited for later recall.
