Psychosis
 

Further, I'm satisfied that Tantra does actually carry a psychosis risk (exactly what that level of risk is hasn't been scientifically established yet). Some links to help you decide;

(That proposal to the American Psychiatric Association was rejected in point of fact - but that isn't to say it won't be included next time etc)

"There are dangers to Tantra. Sense-addiction, insanity/psychosis and abuse of power. At various points on the path, a Tantrika (seeker working with Tantric teachings) may risk (be challenged, tempted or threatened by) one or all of these. Facing these temptations requires Intelligence, and deep commitment to accepting experience `as it is' however that looks."

(Sexual) Abuse

Oxytocin drawbacks

To Ejaculate Or Not To Ejaculate - that is the question;
 
"It is then his choice as to where he wants to send this energy - out with their ejaculate (the prevailing paradigm) or inward for other uses (men who master ejaculation are able to channel this energy into other areas of their being)"

(There are all sorts of arguments ancient and modern about the merits of splitting Orgasm from Ejaculation - modern Medicine has shown the link between Ejaculation and reduced risk of Prostate Cancer - though having no Ejaculation doesn't actually increase the risk)

It has been suggested that the drug Cabergoline has a possible recreational use in reducing or eliminating the male refractory period, thereby allowing men to experience multiple ejaculatory orgasms in rapid succession, and at least two scientific studies support those speculations;

As part of the normal male sexual response, a prolactin surge occurs after orgasm and lasts approximately 1 hour, resulting in a decrease in erectile and ejaculatory potential during this refractory period Inhibition of prolactin could, by similar mechanisms, aid with the resolution of delayed or absent orgasm ..... The efficacy of cabergoline in the treatment of healthy men with orgasmic disorder has not been evaluated, although it might be an effective treatment for this condition because of its inhibitory effect on prolactin, thereby increasing the potential for orgasm.
