Male Sexual Arousal and Orgasms—New Enigmas of Their Activation

Excerpt

I recently wrote a short review about the sexual phenomenon described as the ‘prostate-induced orgasm’ which was illustrated with a highly relevant case history describing some of the problems it can cause [1]. While this sexual activity is much discussed on the internet, typing in ‘websites for prostate-induced orgasms’ into Google produces 383,000 results, but there is a paucity of any scientific appraisal of the physiological mechanisms behind the activity. Basically, males can stimulate the prostate per rectum usually using some commercially developed sexual device (e.g. the instruments produced by Aneros, see http://​Aneros.​com). With time, relaxation and practice, orgasms can be activated that are claimed to be highly erotic and in many cases superior in the pleasure induced to those from penile stimulation, known to the initiated as ‘super orgasms’. These ‘super orgasms’ encourage the user to employ the stimulation repeatedly. The downside of such stimulation, however, is that it can create an addiction to these orgasms to the detriment of those produced by penile stimulation. During the orgasms, semen is not invariably ejaculated indicating a lack of contraction of the pelvic striated muscles, especially the bulbocavernosus, but no investigations have been made to test whether this lack of ejaculation could be due to possible retrograde ejaculation of semen into the bladder. A simple observation to check on this would be to see whether the urine produced after an induction session with prostate orgasms without ejaculation appears ‘milky’ indicating semen in the urine and thus evidence of retrograde ejaculation. More information needs to be gathered about this from prostate stimulation users. Orgasm of reduced strength without ejaculation has been noted in other conditions namely in coitus reservatus [2] and with silodosin treatment, an alpha blocker [3]. This is different from the prostate-induced orgasms without ejaculation that are stronger than those from penile-induced ejaculatory orgasms. In some cases, a situation can develop into the orgasms appearing spontaneously without any direct prostate stimulus per se. …
