Oops, I didn't notice the link to the main page of Religious views on masturbation . 

 Concerning your statement that the link I posted above is a religious site and "not an informed source," I definitely agree with the first claim, but the second claim is somewhat ad hominem, as the article does mention prestigious doctors.  However, I/we would need to find more sources with more points of view to back an argument along the lines of, "A handful of modern scientists believe that masturbation may lead to bodily exhaustion, bone deterioration, and other drastic side effects." 

 Some sections of this article look less biased now that I have skimmed a bit more extensively, but I think the argument I posted above would be an interesting addition to the article.
