Male multiple orgasms

It is possible to have an orgasm without ejaculation (dry orgasm) or to ejaculate without reaching orgasm. Some men have reported having multiple consecutive orgasms, particularly without ejaculation. 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 have also reported that this can produce more powerful ejaculatory orgasms when they choose to have them.

One technique is for the man 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 bladder. It may also cause long term damage due to the pressure put on the nerves and blood vessels in the perineum. Other techniques are analogous to reports by multi-orgasmic women indicating that they must relax and "let go" to experience multiple orgasms^{[citation needed]}. These techniques do not involve suppressing ejaculation in the manner described above, but rather involve mental and physical controls that channel sexual energy throughout the body. Reportedly, successful implementation of these techniques can result in multiple "full-body" orgasms in some men. Recently, a patented prostate stimulator developed by urologists (the Aneros) claims to bring the possibility of intense multiple dry orgasms to many men. This device has been described as "tantric training wheels" as it claims to assist men in training their body to reach these kinds of orgasms.

Some young men have enough stamina, and may experience sufficient stimulation, that the penis never goes flaccid during the refractory period. Very soon after one orgasm, they may be erect and able to experience another orgasm .

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. Furthermore, it is believed 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]

When discussing the difference between orgasm and ejaculation in males, it should be noted that, among those men who began masturbation or other sexual activity prior to puberty, many report having been able to achieve multiple non-ejaculatory orgasms. This capacity generally disappears with the subject's first ejaculation. Some evidence indicates that the orgasms experienced by males prior to puberty are qualitatively similar to the "normal" female experience of orgasm, suggesting that hormonal changes during puberty have a strong influence on the character of male orgasm.^[7]
