A lot has changed in American culture in the past few decades in ways that I believe our health has suffered. And all though I don't have any proof, I believe that since pornography has become easily accessible, and acceptable; as well as new standards for appearances and sexual endeavors, that men (women too, but the comparisons of the act differ too greatly) masturbate at rates much higher than say 50 years ago. Obviously this is complete speculation, but I think it holds some truth. So my question is, is masturbation, at high levels healthy? I've heard that it's good every so often to cleanse the body from a non expert; but most males I know masturbate multiple times each and every day. Does it not affect the body in a negative way? The heart flow, the hormones and stimulants in the body... I would think it would be somewhat of a negative, and obviously not a huge risk, but what are your thoughts? Any factual proof provided would be interesting!
