From the erectile organ

Orgasm is achieved after direct stimulation of the penis or clitoris for a period of time. This stimulation can be caused by sexual intercourse, manual masturbation, oral sex, non-penetrative sex, a sensual vibrator, or an erotic electrostimulation. Any sexual stimulation of the penis or clitoris may eventually result in an orgasm; it may also be achieved by stimulation of other erogenous zones, in the absence of physical stimulation through psychological arousal and as a nocturnal emission or "wet dream".

One technique is to put pressure on the perineum, about halfway between the scrotum and the anus, just before ejaculating to prevent ejaculation. This can, however, lead to retrograde ejaculation, i.e. redirecting semen into the urinary bladder rather than through the urethra to the outside. It may also cause long term damage due to the pressure put on the nerves and blood vessels in the perineum. Men who have had prostate or bladder surgery, for whatever reason, may also experience dry orgasms because of retrograde ejaculation.

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.<ref>Modèle:Cite journal</ref> It can also be said that in some cases, the refractory period can be reduced or even eliminated through the course of puberty and on into adulthood. Later, P. Haake et al. observed a single male individual producing multiple orgasms without elevated prolactin response.<ref>Modèle:Cite journal</ref>

Spontaneous orgasms

Orgasms can be spontaneous, seeming to occur with no direct stimulation. Many people find this to be quite embarrassing but enjoyable. Occasionally, orgasms can occur during sexual dreams.

The first orgasm of this type was reported among people who had spinal cord injury (SCI). Although SCI very often leads to loss of certain sensations and altered self-perception, a person with this disturbance is not deprived of sexual feelings such as sexual arousal and erotic desires. Thus some individuals are able to initiate orgasm by mere mental stimulation. Some non-sexual activity may result in a spontaneous orgasm. The best example of such activity is a release of tension that unintentionally involves slight genital stimulation, like rubbing of the seat of the bicycle against genitals during riding, exercising, when pelvic muscles are tightened or when yawning or sneezing.

From the prostatic structure

Some people are able to achieve orgasm through stimulation of the prostatic structure, which in men is the prostate and in women is Skene's glands; in women the location of Skenes's glands is often known as the g-spot, or Grafenberg Spot, after the physician who first identified the spot as having orgasmic potential. The stimulation can come from receptive intercourse, fingering, fisting, or penetration with a dildo.

Orgasms of this kind can cause both male and female ejaculation. With sufficient stimulation, the prostatic structure can also be "milked." Providing that there is no simultaneous stimulation of the penis or clitoris, prostate milking can cause ejaculation without orgasm. When combined with penile stimulation, some men report that prostate stimulation increases the volume of their ejaculation. The prostatic structure produces a secretion that forms one of the components of ejaculate; in males sperm are transmitted from the ductus deferens into the male urethra via the ejaculatory ducts, which lie within the prostate gland, during orgasm.

Other categorizations of orgasm

Certain types and categorization of orgasm have become widely enough acknowledged to be discussed as distinctive forms of orgasm.

Vaginal orgasm

Anal orgasm

Anal orgasm is an orgasm brought on by anal stimulation, such as from an inserted finger, or sex toy. Some men and women are able to achieve an anal orgasm, as most humans are biologically able to, resulting in a complete or incomplete sexual climax.^{[citation needed]}

In both sexes pleasure can be derived from the nerve endings around the anus and the anus itself. Hence, anal-oral contact can still be pleasurable without stimulation of the clitoris. Anal orgasm has nothing to do with the prostate orgasm, although the two are often confused.<ref>Modèle:Cite book</ref>

Simultaneous orgasm

Simultaneous orgasm (also referred to as mutual orgasm) is a sexual climax achieved by partners at the same time during intercourse.

Other Definitions of "Orgasm"

There is some debate whether certain types of sexual sensation should be accurately classified as 'orgasm', including female orgasms caused by G-spot stimulation alone, and the demonstration of extended or continuous orgasms lasting several minutes or even an hour.<ref>Modèle:Cite book</ref> The question centers around clinical definition of orgasm.

Orgasm is usually defined in a clinical context strictly by the muscular contractions involved.

In these and similar cases, the sensations experienced are subjective and do not necessarily involve the involuntary contractions characteristic of orgasm. However, the sensations in both sexes are extremely pleasurable and are often felt throughout the body, causing a mental state that is often described as transcendental, and with vasocongestion and associated pleasure comparable to that of a full contractionary orgasm.

For this reason, there are views on both sides as to whether these can be accurately defined as orgasms.

Evolutionary function of orgasms

Most male orgasms expel sperm from the body during vaginal intercourse, which can result in conception. Evolutionary biologists have several hypotheses about the role, if any, of the female orgasm in the reproductive process. In 1967, Desmond Morris first suggested in his popular-science book The Naked Ape that female orgasm evolved to encourage physical intimacy with a male partner and help reinforce the pair bond. Morris suggested that the relative difficulty in achieving female orgasm, in comparison to the male's, might be favorable in Darwinian evolution by leading the female to select mates who bear qualities like patience, care, imagination, intelligence, as opposed to qualities like size and aggression, which pertain to mate selection in other primates. Such advantageous qualities thereby become accentuated within the species, driven by the differences between male and female orgasm. If males were motivated by, and taken to the point of, orgasm in the same way as females, those advantageous qualities would not be needed, since self-interest would be enough.

Morris also proposed that orgasm might facilitate conception by exhausting the female and keeping her horizontal, thus preventing the sperm from leaking out. This possibility, sometimes called the "Poleax Hypothesis" or the "Knockout Hypothesis," is now considered highly doubtful.

Other biologists surmise that the orgasm simply serves to motivate sex, thus increasing the rate of reproduction, which would be selected for during evolution. Since males typically reach orgasms faster than females, it potentially encourages a female's desire to engage in intercourse more frequently, increasing the likelihood of conception.

Female orgasm as vestigial

Science writer Natalie Angier has criticized this hypothesis as understating the psychosocial value of female orgasm. Catherine Blackledge in The Story of V, citing studies that indicate a possible connection between orgasm and successful conception, has criticized the hypothesis as ignoring the ongoing evolutionary advantages that result from successful conception.

Medical aspects of orgasm

Physiological responses

In male humans

During orgasm, a human male experiences rapid, rhythmic contractions of the anal sphincter, the prostate, and the muscles of the penis. These contractions typically cause ejaculation -- they force stored semen to be expelled through the penis's urethral opening. The process takes from three to ten seconds, and is usually highly pleasurable.

As a man ages, normally the amount of semen he ejaculates diminishes, and so does the duration of orgasms. This does not normally affect the pleasurable feeling, but merely shortens its duration.

After ejaculation, a refractory period usually occurs during which a man cannot achieve another orgasm. This can be anywhere from less than a minute to several hours, depending on age and other individual factors.

Sensation

As a man nears orgasm during stimulation of the penis, he feels an intense and highly pleasurable pulsating sensation of neuromuscular euphoria. These pulses begin with a throb of the anal sphincter and travel to the tip of the penis. They eventually increase in speed and intensity as the orgasm approaches, until a final "plateau" of pleasure sustained for several seconds, the orgasm.

During orgasm, semen is ejaculated and may continue to be ejaculated for a few seconds after the euphoric sensation gradually tapers off. It is believed that the exact feeling of "orgasm" varies from one man to another,^{[citation needed]} but most agree that it is highly pleasurable.

Orgasm and health

Orgasm, and indeed sex as a whole, are physical activities that can require exertion of many major bodily systems. A 1997 study in the British Medical Journal<ref>Sex and Death, Are They Related?</ref> based upon 918 men age 45-59 found that after a ten year follow-up, men who had fewer orgasms were twice as likely to die of any cause as those having two or more orgasms a week. A follow-up in 2001 which focused more specifically on cardiovascular health found that having sex three or more times a week was associated with a 50% reduction in the risk of heart attack or stroke. (Note that as a rule, correlation does not imply causation).

Orgasmic dysfunction

The inability to have orgasm is called anorgasmia, ejaculatory anhedonia, or inorgasmia. If a male experiences erection and ejaculation but no orgasm, he is said to have sexual anhedonia.

For a variety of reasons, some people choose to fake an orgasm. A recent Redbook survey shows that 52% of women regularly fake orgasms. Only 17% are likely to have an orgasm during sexual intercourse, because the clitoris often is not stimulated enough by intercourse alone. 43% of women report “some kind of sexual problem,” such as inability to achieve orgasm, boredom with sex, or total lack of interest in sex.^{[citation needed]}

If orgasm is desired, anorgasmia is mainly attributed to an inability to relax, or "let go." It seems to be closely associated with performance pressure and an unwillingness to pursue pleasure, as separate from the other person's satisfaction. Often, women worry so much about the pleasure of their partner that they become anxious, which manifests as impatience with the delay of orgasm for them. This delay can lead to frustration of not reaching orgasmic sexual satisfaction. Psychoanalyst Wilhelm Reich, in his 1927 book The Function of the Orgasm was the first to make orgasm central to the concept of mental health, and defined neurosis in terms of blocks to having full orgasm. Although orgasm dysfunction can have psychological components, physiological factors often play a role. For instance, delayed orgasm or the inability to achieve orgasm is a common side effect of many medications.

In tantric sex

Tantric sex is the ancient Indian spiritual tradition of sexual practices. It attributes a different value to orgasm than traditional cultural approaches to sexuality. Some practitioners of tantric sex aim to eliminate orgasm from sexual intercourse by remaining for a long time in the pre-orgasmic and non-emission state. Advocates of this, such as Rajneesh, claim that it eventually causes orgasmic feelings to spread out to all of one's conscious experience.<ref>Modèle:Cite book</ref><ref>Modèle:Cite book</ref>

Some advocates of tantric and neotantric sex claim that Western culture focuses too much on the goal of climactic orgasm, which reduces our ability to have intense pleasure during other moments of the sexual experience. Eliminating this enables a richer, fuller and more intense connection.<ref>Modèle:Cite book</ref>

These practices should not be confused with Buddhist tantra (Vajrayana).
