I knew there was a good excuse for masturbating.
I attended a party at a private club in Houston's Medical Center twenty years ago. There a cardiologist taught me how to smoke a cigar. Also several others very seriously stated that they believed that the declining ejaculation frequency in aging contributes to prostate problems. They told me that if you find yourself later in life without a sex partner, males need to be "their own best friend" and rub one out routinely. However, please don't tell their Priest, Ministers, and Rabbis that they said this. I thought they were making fun of me, because I was the only male there not a doctor. A few years later I was getting my first "digital exam" and the examining doc told me this too. That the human male is made to cream regularly and those that do report fewer urological problems.
I asked why there has been no controlled study. The reply was, "the fear of ridicule."
