I was recently told by a chinese acquaintance of an alternate taoist sexual technique he was taught- It involves the male getting himself to the point where he is about to emit and then dousing his bits with cold water, wait until you're soft again, and repeat ten times. This is done 3 times a week and is said to greatly improve the strength and health of the genitals, plus improve 'staying power.' Anyone know whether this would be harmful or not, specifically to the prostate? I read elsewhere that the problems with some these taoist techniques, from a health perspective, is that by repeatedly filling the prostate with semen but then not allowing it to expunge, problems result. Another side effects , I have been told, that may be associated with certain taoist sexual techniques are testicular cancer.
