Human male orgasm
In a human male orgasm, there are rapid, rhythmic contractions of the prostate, urethra and the muscles at the base of the penis, which (in the adult) typically forces stored semen to be expelled through the penis' urethral opening, in a process known as peristalsis. This is referred to as ejaculation. The process generally takes from 3 to 10 seconds and is usually extremely pleasurable.

Orgasm is generally induced by direct stimulation of the penis. Some men experience heightened orgasm by direct stimulation of the prostate through the perineum or rectum.

As a man ages, it is normal for the amount of ejaculate to diminish, and hence, the length of time the man sustains orgasm also diminishes somewhat. This does not affect the pleasurable feeling of orgasm at all, it merely shortens the duration of it.

Following ejaculation, a refractory period usually occurs during which a man cannot have another orgasm. This period can be anywhere from less than a minute to over half a day, depending on age and other individual factors. A few cases have been reported of men who appear to have no refractory period at all. Scientists theorize that a pituitary gland difference may cause this unique ability.

[edit]
Male prostate orgasm
Some men are able to achieve ejaculation or orgasm through intra-anal stimulation of the prostate gland. Men reporting the sensation of prostate stimulation often give descriptions similar to women's accounts of G-spot stimulation. Other men report finding anal stimulation or penetration of any kind to be painful, or simply that they find no profound pleasure from it. With sufficient stimulation, the prostate can also be "milked". Providing that there is no simultaneous stimulation of the penis, prostate milking can cause ejaculation without orgasm. When combined with penile stimulation, some men report that prostate stimulation increases the volume of their ejaculation, and provides an enhanced and more pleasurable version of the standard male orgasm.

[edit]
Male multiple orgasms
It is possible to have an orgasm without ejaculation (dry orgasm) or to ejaculate without reaching orgasm. Some men report that the ability to consciously separate orgasm and ejaculation has allowed them to achieve multiple orgasms. Men who have practiced this technique extensively report that they can sometimes experience a continuous "wave" of orgasm. This can last, in theory, indefinitely, but in practice is limited by the man's ability to concentrate/meditate, or "surf the wave." Reaching between ten and twenty orgasms in one session is reportedly common for many practitioners. In recent years, a number of books have described various techniques to achieve multiple orgasms. Most multi-orgasmic men (and their partners) report that refraining from ejaculation results in a far more energetic post-orgasm state. Additionally, some men who have become adept at this practice also report more powerful ejaculatory orgasms when they choose to have them. Some of the most basic techniques for achieving multiple orgasms require that the man "hold on" to the perineum to prevent ejaculation. More advanced techniques are analogous to reports by multi-orgasmic women indicating that they must relax and "let go" to experience multiple orgasms.

Some young men, however, have enough stamina so that the penis, given sufficient stimulation, never goes flaccid during the refractory period. In such cases it is unnecessary to try yoga and meditation techniques that call for control over one's body. It is actually quite painful to try to interfere with the ejaculation response once it has been triggered. Generally within 30-45 minutes of the onset of the first refractory period, such men are able to have an orgasm again.

Internet rumors and a few scientific studies have pointed to the hormone prolactin as the likely cause of the male refractory period. Because of this, there is currently an experimental interest in drugs which inhibit prolactin, such as Dostinex (also known as Cabeser, or Cabergoline). Anecdotal reports on Dostinex suggest it may be capable of eliminating the refractory period altogether, allowing men to experience multiple ejaculatory orgasms in rapid succession. At least one scientific study supports these claims.[4] Dostinex is a hormone altering drug and has many potential side effects. It has not been approved for treating sexual dysfunction. Another possible reason may be an increased infusion of the hormone oxytocin. Futhermore, it is belived that 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 male was conducted at Rutgers University in 1995. During the study, six fully ejaculatory orgasms were experienced in 36 minutes with no refractory period in evidence.[5] 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.[6]

[edit]
Human female orgasm
In a human female orgasm, orgasm is preceded by moistening of the vaginal walls, and an enlargement of the clitoris due to increased blood flow trapped in the clitoris's spongy tissue. Some women exhibit a sex flush, a reddening of the skin over much of the body due to increased blood flow to the skin. As a woman comes closer to having an orgasm, the clitoris moves inward under the clitoral hood, and the labia minora (minor lips) become darker. As orgasm becomes imminent, the vagina decreases in size by about 30% and also becomes congested from engorged soft tissue. The uterus then experiences muscular contractions. A woman experiences full orgasm when her uterus, vagina and pelvic muscles undergo a series of rhythmic contractions. The majority of women consider these contractions to be very pleasurable.

After the orgasm is over, the clitoris re-emerges from under the clitoral hood, and returns to its normal size in less than 10 minutes. Unlike men, women either do not have a refractory period or have a very short one and thus can experience a second orgasm soon after the first; some women can even follow this with additional consecutive orgasms. This is known as having multiple orgasms. After the initial orgasm, subsequent climaxes may be stronger or more pleasurable as the stimulation accumulates. Research shows that about 13% of women experience multiple orgasms; a larger number may be able to experience this with the proper stimulation (such as a vibrator) and frame of mind. However, some women's clitorises are very sensitive after orgasm, making additional stimulation initially painful. It is possible to engage in deep, rapid breaths while continuing stimulation and making a conscious intention to release the pain and tension. Doing this can allow for the intense stimulation to be interpreted not as painful but as intensely pleasurable.[7]

[edit]
Achieving multiple orgasm
Some women can achieve multiple orgasms: a series of orgasms, one after another with possibly increased intensity after the first. The great exertion involved can be blissfully debilitating for quite some time after.

This kind of orgasm would normally involve stimulation of the woman's clitoris rather than the vagina. Some women can do this manually using their fingers taking a pause of two or three seconds between each. When using their hands, women can insert fingers up the vagina, wriggling their fingers to stimulate the G-spot, also the women may also massage the clitoris repeatedly.

A vibrator applied directly to the clitoris can enable women who are not practiced in using their fingertips. A vibrator used this way can be applied almost continuously to bring about orgasms that seem less separated. A battery powered tooth brush that vibrates with an oscillatory rotational motion is preferred by some for whom it is more effective than a vibrator.

[edit]
The evolutionary purpose of orgasms
Evolutionary biologists put forward several hypothesis for explaining the role of the female orgasm in terms of the reproductive process. In 1967, Desmond Morris first suggested in his pop-science book The Naked Ape that female orgasm evolved to encourage physical intimacy with a male partner and help reinforce the pair bond. He additionally proposed that orgasm might facilitate conception by exhausting the female and keeping her horizontal, thus preventing the sperm from leaking out. This possibility, sometimes dubbed the "Poleax hypothesis" or the "Knockout hypothesis", is now considered as highly doubtful.

Other theories have been proposed based on the idea that the female orgasm might increase fertility. The 30% reduction in size of the vagina could, for example, help clench onto the penis (much like, or perhaps caused by the pubococcygeus muscles), which would make it more stimulating for the male (thus ensuring faster or more voluminous ejaculation). The British biologists Baker and Bellis have also suggested that the female orgasm may have an "upsuck" action, retaining favorable sperm and making conception more likely.[8] They posited a role of female orgasm in sperm competition.

A 1997 Learning Channel documentary on sex had fiber optic cameras inside the vagina of a woman while she was having sexual intercourse and experiencing an orgasm. During her orgasm, her pelvic muscles contracted, and her cervix dipped into a pool of semen in the vagina making conception more likely.[9]

The fact that women tend to orgasm easier when they are ovulating suggests that it is tied to increasing fertility.[10]

Other biologists, such as Stephen Jay Gould, suggest the female orgasm is analogous to the male nipple—an evolutionary holdover which, though associated with pleasure in the context of sexual behaviour, has no distinct biological function.

Still others surmise that the orgasm simply serves to motivate sex, thus increasing the rate of reproduction and helping ensure the species' survival.

[edit]
Orgasm as vestigial
The clitoris is homologous to the penis, that is, the penis and clitoris develop from the same embryonic structure. It has been claimed by some researchers, such as Stephen Jay Gould that the clitoris is vestigial in the female, and that female orgasm serves no particular evolutionary function.

Proponents of this theory, such as Dr. Elisabeth Lloyd, point to the relative difficulty of achieving female orgasm through vaginal sex, and limited evidence for increased fertility after orgasm.

Feminists such as Natalie Angier have criticized that this theory understates the psychosocial value of female orgasm. Catherine Blackledge in The Story of V has criticized the theory from a more scientific standpoint, citing studies that indicate a possible connection between orgasm and successful conception.

[edit]
Genetic basis of individual variation
A 2005 twin study found that one in three women reported never or seldom achieving orgasm during intercourse, and only one in ten always orgasmed. This variation in ability to orgasm, generally thought to be psychosocial, was found to be between 34-45% genetic. The study, examining 4000 women, was published in Biology Letters, a Royal Society journal.[11][12]

According to the researchers, heritability suggests that evolution has a role. They suggested this characteristic might have evolved because it helped females select males who were the most powerful and thoughtful, who would be the most likely to hang around as a long-term partner and be a better bet for bringing up offspring. In this theory, women who orgasm easily may have been satisfied with mates who were less skilled. While in certain cultures it has been posited that women who are more orgasmic may be more promiscuous, there has to date been no confirmation of this in a scientific study.

[edit]
Vaginal versus clitoral orgasms
A distinction is sometimes made between clitoral and vaginal orgasms in women. An orgasm that results from combined clitoral and vaginal stimulation is called a blended orgasm. Many doctors have claimed that vaginal orgasms do not exist, and that female orgasms are obtained only from clitoral arousal. Recent discoveries about the size of the clitoris—it extends inside the body, around the vagina—would seem to support this theory. On the other hand, other sources argue that vaginal orgasms are dominant or more "mature". However, these arguments are frequently criticized on the ground that they adhere to an androcentric view of sexuality which privileges the male sexual organ.

This latter viewpoint was first promulgated by Sigmund Freud. In 1905, Freud argued that clitoral orgasm was an adolescent phenomenon, and upon reaching puberty the proper response of mature women changes to vaginal orgasms. While Freud did not provide evidence supporting this basic assumption, the consequences of the theory were greatly elaborated thereafter.

In 1966, Masters and Johnson published pivotal research into the phases of sexual stimulation. Their work included women as well as men, and unlike Kinsey previously (in 1948 and 1953), set out to determine the physiological stages leading up to and following orgasm.[13] One of the results was the promotion of the idea that vaginal and clitoral orgasms follow the same stages of physical response. Additionally, Masters and Johnson argued that clitoral stimulation is the primary source of orgasms.

This standpoint was once adopted by feminist advocates, to the extent that some held that the vaginal orgasm was a mirage, created by men for their convenience. In fact, while many women can only experience orgasm with clitoral stimulation, either alone or in addition to vaginal stimulation, other women can only experience orgasm with vaginal stimulation. Consequently, modern feminists work to raise awareness that both vaginal and clitoral orgasms are possible. Their beliefs hold that a woman's sexual choices are personal ones, and must be respected.

A new understanding of vaginal orgasm has been emerging since the 1980s. Many women report that some form of vaginal stimulation is essential to subjectively experience a complete orgasm, in addition to or instead of external (clitoral) stimulation. Recent anatomical research has pointed towards a connection between intravaginal tissues and the clitoris. It has been shown that these tissues have connecting nerves. This, combined with the anatomical evidence that the internal part of the clitoris is a much larger organ than previously thought could also explain credible reports of orgasms in women who have undergone clitoridectomy as part of so-called female circumcision.

In some cases it is possible for women to orgasm through stimulation of secondary sexual organs (e.g. breasts), and in very rare cases, without any direct stimulation to the genitalia or the other specific erogenous zones, but instead stimulation of the non-specific zones (e.g. neck).

Some women experience orgasm while giving birth. In addition, orgasm can be spontaneous, many people find this to be quite embarrassing but enjoyable, seeming to happen with no direct stimulation. Occasionally, orgasm can occur during sexual dreams.

[edit]
Anal orgasm
New studies have shown that women are able to achieve anal orgasms without any other stimulation. Anal orgasms can occur in a couple of different manners. One is an orgasm achieved during the process of anal sex (when the erected penis is inserted in the anus of a woman, and then ejaculated inside the anus). The other is when a finger is placed into the anus and wiggled back and forth. This sort of stimulation is known to bring some women to orgasm within the space of 30 seconds. Numerous non western cultures, as well as ancient cultures, have records of this fact. The reason for the recent interest scientists have shown towards this form of orgasm is due to the taboo and moral restrictions related to anal sex, which prevailed in West cultures until the second half of the twentieth century. However, Freud had stated that the female sexual organ was a composite of oral, anal and vaginal orifices.

[edit]
Controversy: Definition of orgasm
There is controversy surrounding male multiple orgasms, and female G-spot (vaginal, not blended) orgasms, because some feel that they do not fit within the clinical definition of orgasm. Male multiple orgasms, while pleasurable, often do not involve involuntary contractions. Similarly, there are not always contractions in female orgasms resulting from stimulation of the g-spot alone, without stimulation of the clitoris. However, both of these sensations in the two sexes are extremely pleasurable, and are often felt throughout the body, creating a mental state that is often described as transcendental. Because of this, some persons feel that these experiences can be accurately defined as orgasms. Others insist that orgasm is defined strictly by muscular contractions, and that these other sensations are too subjective to be quantified as orgasms.




[edit]
Orgasmic dysfunction
The inability to have orgasm is called anorgasmia, ejaculatory anhedonia, or inorgasmia. In situations where orgasm is desired, anorgasmia is mainly thought of as being caused by 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. It was the psychoanalyst Wilhelm Reich, in his 1927 book The Function of the Orgasm, who first made orgasm central to the concept of mental health and defined neurosis in terms of blocks to having full orgasm.

For a variety of reasons, some people choose to fake an orgasm.

If a male experiences erection, ejaculation, but no orgasm he said to have Sexual anhedonia.

[edit]
Drugs and orgasm
Certain drugs have been reported to have enhancing effects on orgasm. Alkyl nitrites are used by some men to enhance orgasm. Marijuana has widely been reported to enhance and prolong both male and female orgasms, while at the same time delaying ejaculation. Stimulant, psychedelic, and Ecstasy drug users of both sexes sometimes report heightened sexual pleasure. Some male cocaine users report rubbing the glans of their penis with cocaine in order to numb it and delay ejaculation. The use of recreational drugs to enhance orgasm may be unreliable or have hazardous side effects.

Studies have indicated that each of the three major erectile dysfunction drugs have different reported effects on orgasm. Anecdotal evidence suggests that women have enhanced orgasms with Sildenafil (commercially known as Viagra). In men, Sildenafil has varying effects on orgasm. Some men report enhancement, while others report that while they can achieve an erection with Sildenafil, their orgasms feel "hollow". Vardenafil behaves very similarly to Sildenafil. Tadalafil, a newer drug, in addition to treating erectile dysfunction over longer periods of time, is said to enhance orgasm and shorten the male refractory period. Some drugs, such as Cabergoline, are reported to shorten the refractory period without having any effect on erections or orgasms.

Studies have also proven that a variety of opiate based drugs both natural and synthetic, such as the painkillers codeine, morphine, and heroin, and the common over-the-counter cough suppressant Dextromethorphan, makes achieving orgasm extremely difficult.

Imipramine, a tri-cyclic anti-depressant (TCA), is known to cause spontaneous orgasms among patients who take it.

While prescribing drugs to solve problems, many sex therapists discourage the regular use of drugs to enhance sex, because of the elevated risk of dependency.

Inversely, a number of anti-depressant drugs, especially those in the class of selective serotonin-reuptake inhibitors (SSRIs), have as a side effect a delay or even an inability to achieve orgasm. One potential basis of this side effect is penile anesthesia.

[edit]
Orgasm in Tantric sex
In the Asian spiritual tradition of sexual practice known as Tantric sex, orgasm has a different value than in other cultural approaches to sexuality. Some practitioners of Tantric sex aim to eliminate orgasm from sexual intercourse by remaining for long periods of time at the pre-orgasmic state. According to some advocates of Tantric sex, such as Rajneesh, practising Tantric sex without orgasm will eventually lead to orgasmic feelings spreading out to all of conscious experience. Some current advocates of Tantric sex claim that in Western culture sexuality is put in the service of orgasm in a way that reduces the ability to have intense pleasure during each moment of sexual experience, and consequently that eliminating the striving toward orgasm enhances the pleasure to be derived from all aspects of sexual experience.

[edit]
Orgasm in non-humans
The mechanics of the male orgasm are similar in most mammals, and females of some mammalian species have clitorises. There is evidence that some non-human animals, particularly primates, can experience orgasm in ways similar to humans.

[edit]
Non-sexual meaning of the word "orgasm"
Dictionaries still indicate that the word "orgasm" can refer to any peak of emotional intensity—a "climax" in the non-sexual sense. Nowadays, the word would be likely to be misunderstood if used in that way; such usage is vanishingly rare. It does, however, occur without a primarily sexual meaning in literature written prior to the sexual revolution:

Here in this cathedral at Burgos was the record of an incredible spiritual energy. … Those who had built and carved and painted here had been more than happy. They had left the record of their ecstasy in a divine orgasm of stone.[14]
In reference to a horse which is calming down after being "spooked:"

It was a very weak and very sick mare he rode, stumbling and halting, afflicted with nervous jerks and recurring muscular spasms—the aftermath of the tremendous orgasm through which she had passed.[15]
In the following sentence, a newcomer to the Arctic is impressed with Malemute Kid's forceful personality. ("Breathing heavily" here means "asleep.")

Malemute Kid was already breathing heavily; but the young mining engineer gazed straight up through the thick darkness, waiting for the strange orgasm which stirred his blood to die away."[16]

Hello,
There are many natural ways to cure premature ejaculation. A proven natural method can be found on this site http://www.goobypls.com/r/rd.asp?gid=565

Recent polls have shown that the average length of intercourse is usually anywhere between 2 to 12 minutes. Most often those diagnosed with premature ejaculation climax in less than a minute or two, and there are even those who ejaculate before there is any sort of penetration. In all actuality, “too short” is really just a matter of opinion. The most important factor is if a man feels that he is unable to control his ejaculation and is frequently climaxing before he would like. Any man who feels that this is a problem for him may be suffering from some form of premature ejaculation.

Premature ejaculation is caused by specific things that you do before and during sex. Most of the time without even realizing it. Read here https://tr.im/gDpAO

Premature ejaculation is not some gene you're born with, the result of your penis size or a part of your personality that you can never change.
