Despite what they told you, rubbing one out is good for you.

Researchers in Australia have discovered that men who masturbate frequently reduce their risk of prostate cancer. It is believed that frequent ejaculation rids the prostate of carcinogens that build up over time. The researchers studied 1,000 men who had developed prostate cancer, and another 1,200 men who had not. They discovered that the men who had frequent ejaculations between 20 and 50 years of age were less likely to develop cancer.

So, set those guilt feelings aside, and feel free to spank that monkey all the time.
