An article claims that
sexual abstinence is bad for you:
Fans of abstinence had better be sitting down. "Saving yourself" before the big game, the big business deal, the big hoedown or the big bakeoff may indeed confer some moral benefit. But corporeally it does absolutely zip. There's no evidence it sharpens your competitive edge. The best that modern science can say for sexual abstinence is that it's harmless when practiced in moderation. Having regular and enthusiastic sex, by contrast, confers a host of measurable physiological advantages, be you male or female.
Its findings, published in 1997 in the British Medical Journal, were that men who reported the highest frequency of orgasm enjoyed a death rate half that of the laggards.
Other claimed benefits of regularly gettin' it on include: improved sense of smell, weight loss and overall fitness, pain relief, and reduced risks of heart disease, cancer, depression and incontinence.
