Orgasm

An orgasm, also known as a sexual climax, is a pleasurable physical, psychological or emotional response to prolonged sexual stimulation. It is often accompanied by a notable physiological reaction, such as ejaculation, blushing or spasm and may be followed by aftershocks.

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 force stored semen to be expelled through the penis's urethral opening. This is referred to as ejaculation. The process usually takes from 3 to 10 seconds. The process is usually, but not always, 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 with a finger or dildo inserted in the anus.

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 very few cases have been reported of men who appear to have no refractory period at all. Scientists theorize that a pituitary gland disorder or difference may cause this unique ability.

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.

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 and "surf" the "wave". In recent years a number of sex manuals for men have delved into this technique. Men who have become adept at this practice also report more powerful ejaculatory orgasms when they choose to have them. It is uncertain whether this is a result of more time between ejaculations, or a direct result of practice. Interestingly, the male multiple orgasm requires that the man "hold on", maintaining control to prevent ejaculation. In contrast, multi-orgasmic women sometimes report that they must relax and "let go" to experience multiple orgasms.

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. No scientific study explicitly supports these claims, but a German study cites unspecific increase in sexual pleasure. Dostinex is a hormone altering drug and has many potential side effects. It has not been approved for treating sexual dysfunction.

To date, the only known 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. The study was subsequently published in the "Journal of Sex Education and Therapy" (1998; Volume 23, No. 2; pp 157-162).
