An orgasm (sexual climax) is the conclusion of the plateau phase of the sexual response cycle, and may be experienced by both males and females. Orgasm is characterized by intense physical pleasure, controlled by the involuntary, or autonomic, nervous system.[1] It is accompanied by quick cycles of muscle contraction in the lower pelvic muscles, which surround the primary sexual organs and the anus. Orgasms are often associated with other involuntary actions, including muscular spasms in other areas of the body, a general euphoric sensation, and frequently, vocalizations.

After orgasm, humans often feel tired and a need to rest. This is attributed to the release of prolactin.[2] Prolactin is a typical neuroendocrine response in depressed mood and irritation.[3] Ongoing research at the University Medical Center of Groningen, the Netherlands, studies brain events that accompany orgasm in men and women. Techniques used involve Positron Emission Tomography (PET) and fMRI. Male and female brains act almost the same during orgasm. Brain scans showed that large parts of the cerebral cortex temporarily reduced their activity.Free Orgasm movies

Achieving orgasm

One of the main ways of achieving orgasm is by direct or indirect stimulation of the penis or clitoris. Such stimulation can come from a variety of activities, including but not limited to sexual intercourse, manual masturbation, anal sex, oral sex, non-penetrative sex, a sensual vibrator, or an erotic electrostimulation. Orgasm may also be achieved by stimulation of the nipples or other erogenous zones. In the absence of physical stimulation, orgasm can be from psychological arousal alone, or during dreaming (a nocturnal emission or "wet dream" in males).

Important in sexual stimulation are internal glands, called the Skene's glands in women and the prostate in men, two homologous structures. In common use, the term G-spot refers to these areas.

The stimulation can come from receptive intercourse, fingering, fisting, or penetration with a dildo.

With sufficient stimulation, the prostatic structure 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.

Vaginal orgasm

The female body can achieve orgasm from stimulation of the clitoris and from stimulation of the G-spot. The Gräfenberg spot, or G-spot, is a small area behind the female pubic bone surrounding the urethra and accessible through the anterior wall of the vagina. Many scientists believe that only certain women possess a G-spot[citation needed]. The G-spot orgasm is sometimes referred to as "vaginal," because it results from stimulation inside the vagina, including during sexual intercourse. However, only stimulation of the G-spot, and not other intravaginal stimulation, results in a "vaginal orgasm."[citation needed]

The "two-orgasm theory" (the belief that in women there is a vaginal orgasm and a clitoral orgasm), has been criticized by feminists such as Ellen Ross and Rayna Rapp as a "transparently male perception of the female body".[5] The concept of purely vaginal orgasm was first postulated 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 provided no evidence for this basic assumption, the consequences of the theory were greatly elaborated, partly because many women felt inadequate when they could not achieve orgasm via vaginal intercourse that involved little or no clitoral stimulation.

In 1966, Masters and Johnson published pivotal research about the phases of sexual stimulation. Their work included women and men, and unlike Alfred Kinsey earlier (in 1948 and 1953), tried to determine the physiological stages before and after orgasm.[6] One of the results was the promotion of the idea that vaginal and clitoral orgasms follow the same stages of physical response. Masters and Johnson also argued that clitoral stimulation is the primary source of orgasms.

Recent discoveries about the size of the clitoris - it extends inside the body, around the vagina[7] - complicate or may invalidate attempts to distinguish clitoral vs. vaginal orgasms. Recent anatomical research shows that there are nerves connecting intravaginal tissues and the clitoris.[citation needed] This, with the anatomical evidence that the internal part of the clitoris is a much larger organ than previously thought, could explain credible reports of orgasms in women who have undergone clitorectomy as part of female circumcision. The link between the clitoris and the vagina is evidence that the clitoris is the 'seat' of the female orgasm and is far more wide-spread than the visible part most people associate with it. But it is possible that some women have more extensive clitoral tissues and nerves than others, and so that some women can achieve orgasm only by direct stimulation of the external part of the clitoris.
