I think you're on crack. What is wrong with pleasure? What is wrong with loving yourself enough to give yourself pleasure? Do you really think a woman should rely solely on a man to give her pleasure? If that were the case, the number of women that have never experienced an orgasm would decline drastically below the pathetic number that it already is today!
As for the man with impotence, most cases of impotence are psycho-somatic not brought on by any physical/medical problem and certainly not because of excessive masterbation!
I'm really flabergasted that someone feels this way. Now don't get me wrong, I'm not a routinely active masterbator. I don't own any toys or anything, but there is nothing wrong with feeling pleasure. After all, IT'S A NORMAL BODY PROCESS AND NOTHING TO BE ASHAMED OF!
