The opinion of those who in the camp of "For!"
If conditionally to divide the defenders and opponents of Masturbation in the first camp will be supporters. They claim that neurosis, mental and physical illness, a work of fiction homegrown luminaries from science, just to scare the younger generation.
In the mythology of Masturbation for the entire historical period got a lot, from epilepsy to sexually transmitted diseases.
Among the dispelling of myths about the effects of Masturbation on human: nervous disorders, blindness, hair on the hands (palms), a tendency to early impotence, difficulties in sexual life, family problems, inability to create a viable unit of society and to procreate healthy offspring.
The defenders of Masturbation I think that this is all fiction, and moderate Masturbation is only good because it supports the body in tone, allows him to relax, relieves stress, regulates the blood sugar level, improves metabolism, and replaces the sexual act, if the latter is not possible due to various reasons.
Camp "Against!"
Opponents of Masturbation mostly not professionals, and people read too many bad or just plain old literature on the issue. If we consider the ideas that circulated around Masturbation at the beginning of the last century, many psychologists and psychiatrists believed that from this scourge needs to be treated even with electric shocks. And the usual night male erections should suppress a special metal or leather devices which are used to Wake the host when he was "undesirable" moments.
Today, all physiologists agree that the night erection is normal and even indicator of the health of men.
That's not stopping opponents of Masturbation, stating that this problem needs solving. Children and Teens convicted of it, you need to fully wean and punished for "Masturbation". As well as to protect them from anything that can stimulate libido.
If you do not go to extremes
Perhaps this is rational, if not extreme, that flow into both sides. As the Roman proverb says "New quid nimis!" (Nothing too!).
In any case, including Masturbation, it is best to stick to the Golden mean with its moderation and reasonable approach.
If we take the average assessment of the phenomenon, and the opinion of most physiologists, psychologists, psychiatrists, moderate Masturbation, hygiene, without pronounced emphasis on the self-satisfaction (this is when the idea becomes obsessive) is not hazardous to health. Dangerous to mislead young people, to influence immature minds negatively, even to punish them for it. What punishment can cause sexual problems in the future. Therefore, moderation and the only moderation will keep you in good health and peace of mind.
