I am not a doctor but i had the same problem. First of all you have to realize the damage an excessive
masturbation can bring to you, although in medical term masturbation is considered as a normal and could even be a healthy activity during young age, and masturbation is particularly common in male.
Based on my personal experience and research, the problems of having masturbation can be
- addiction; like all other activities including gambling,
smoking, on drug, masturbation can be easily addictive. The more you do it the more you become addicted to it.
- unrealistic imagination; everytime you masturbate your mind will render all kinds of pictures or imagination of naked women having sexual activity with you, you tend to have unrealistic demand or expectation from real sex.
- think of sex all the time; once you indulge yourself in masturbation your mind will be full of sexual acts all the time, everytime you see gorgeous lady you may also imagine her naked body, you just cannot concentrate on something else, believe me, this is absolutely a nightmare.
- premature ejaculation; excessive masturbation can cause premature ejaculation, we don't need a scientist to prove it, many sufferers have a chronic habit in masturbation.
- tiredness; our body needs time, energy and nutrient to generate sperms, everytime you ejaculate your body will have to work harder to replenish the lost "stock", inevitably you will become tired.
- possible cause of dysfunctional erectile problem; I believe we need to maintain a balance and healthy lifestyle to keep our body going, any excessive activity can only cause harm to our body, we ought to give our body a rest.
Although doctors don't regard masturbation as a problem but I think it does more harm than good to us, it is just like what the bible says, all things are permissible but not all things are beneficial, it is just not worth it.
Doing exercise may help to distract your focus, but the long term solution is to get married and have a healthy sex life with your wife.
Final word, we just should NOT encourage masturbation. period.
