It seems a study has shown a relationship between frequent ejaculation and lower chances of prostate cancer.

It appears from the study that ejaculating 21 times or more per month can reduce the chance of cancer by up to 22%.
Well that seems like a reasonable prophylactic treatment to me.
And it doesn't matter whether it is intercourse or masturbation.
So instead of the old Army wake up -"Drop your cocks and grab your socks", maybe we men should be "Dropping our socks and grabbing our cocks"......
