7. Why Sex Is Good – Reduce The Risk Of Developing Prostate Cancer
Men who have sex frequently could be protected against developing prostate cancer, one of the most common types of cancer in men in the United States.
According to a study conducted by Michael Leitzmann and published in the Journal of the American Medical Association, men who have sex for 21 times a month or so are a third less risk to develop prostate cancer compared with men who have sex for 4 to 7 times a month 
The reason is that having sex frequently helps the prostate gland clear out carcinogens, & materials that can orchestrate the development of many carcinogens. In addition, draining out prostate fluid regularly may stop crystalloid microcalcifications, linked to prostate cancer – from developing the prostate duct.
