As if masturbation didn't already provide enough of a payoff, a recent Australian study found that DIY sex may also help prevent prostate cancer.
The study of 2,338 men showed that the guys who masturbated five or more times a week were 34 percent less likely to develop prostate cancer by age 70 than those who handled matters less often.
"Seminal fluid contains substances that are carcinogenic," says Graham Giles, Ph.D., the lead study author. "Regular ejaculation may help flush them out."
And in case you're wondering, no, masturbating more than once a day won't offer more protection, and yes, straight-up sex works, too. But before you have unprotected nookie with your partner, be sure she's been tested for cytomegalo-virus, a type of herpes recently found in cancerous prostate tissue.
