Looks like my prostate is nice and healthy:

Australian researchers have reported that frequent masturbation may lower a man’s risk of developing prostate cancer. A survey of men found the more frequently a man masturbates between the ages of 20 and 50, the less likely they are to get prostate cancer. In fact, those who masturbated more than five times a week were one-third less likely to develop prostate cancer.

So according to this formula (carry the one, add five, divide by two)…I’m about two-thirds less likely to develop prostate cancer (and that was just while writing this post).
