Even when a person indulges in masturbation frequently, the penis never shrinks and becomes small. Once any part or organ of the human body has attained its maximum size, it will never become small unless it is partially cut off accidentally or surgically. Special food and exercise will make the penis grow big. Whatever that is good for other body parts is also good for sex organs. Masturbation leads to nervous breakdown.
Masturbation is a normal physiological activity.
Only, physiologically or emotionally sub-normal people do not masturbate. Vasectomy makes a man impotent. In fact, by removing the fear of pregnancy, sexual desire and the performance are increased. Men have stronger sexual urges than women. Sexual urge is equal in both the sexes.
