1) Having read a few posts related to the question, "Is masturbation harmful?", most of the answers I've seen seem to suggest that the only possible harm could be psychological, in the sense that masturbation may be a distraction from one's normal routine.
What about the actual PHYSICAL side effects? Some things can not be dismissed as mere "wives' tales"! For example, when I masturbate often, I do notice a darkening under my eyes. I am only 28, but having been at this a while, it does seem as though I can not as easily become erect, or stay erect for as long as I used to. I may not have grown hair on my palms, but I have noticed (and I'm willing to concede that there may be no causal relationship here) that I have become somewhat hairier, in all the wrong places.
Please set the record straight as to what, if any, harmful PHYSICAL side effects may result from masturbation, and why, in the face of my testimonial and no doubt countless others, such symptoms as I have described are dismissed by yourself and your peers as "myths."
2) Does masturbation affect your growth if you are not yet fully grown?
