I was doing something good . . .

and didn't even know it.

I started doing some research on male ejaculation (trying to figure out why I sometimes have all the sensations of an orgasm but no ejaculation) and ran across this quote from a study:

[T]he protective effect of ejaculation is greatest when men in their twenties ejaculated on average seven or more times a week. This group were one-third less likely to develop aggressive prostate cancer when compared with men who ejaculated less than three times a week at this age.

I guess all those escorts and massage girls I saw, and masturbating I did in my twenties turned out to be a good thing. ;-)
