Flutterby™! : Masturbation still healthy

Masturbation may prevent prostate cancer:

The researchers surveyed more than 1,000 men who had developed prostate cancer, and 1,250 men who had not. They found that men who had ejaculated the most between the ages of 20 and 50 were the least likely to get cancer. Men who ejaculated more than five times each week were a third less likely to develop prostate cancer.

I think we've talked about this study or a similar one before, because I remember considering that ejaculations from partner sex had higher risks from other factors, which is why masturbation caused such a huge spike.
