No one can masturbate in excess.

Your body has an auto-stop mechanism whereby you don’t go on! Masturbating repeatedly hundreds of times in a day. The body takes care and has an auto control mechanism whereby you cannot exceed your body limits.

The following analogy explains the above sentence beautifully:
If you are hungry for two days and are invited to a party where gulab jambus (Indian sweet dish) is being served. People are still chatting and no one has even started eating. However, you have finished eating three plates even before others in the party have started. While eating people notice that you have taken twenty-one servings of the sweet dish. Now you are teasingly goaded to eat more and create a record. You eat three additional dishes and say, “Now I am done. That’s enough”. A person coaxes you to eat just one more dish and offers a reward of five thousand rupees/dollars/pounds/whatever. “No way, not a single more”, you say. A doctor offers you a tablet and says you will be able to eat more if you take the pill. You reply, “There is no place even for the pill”. Even if one of the party guys threatens with a gun on your head, you don’t eat more.

Body has an auto mechanism to stop excess food intake. We say, ‘My stomach is full.’, ‘I am done.’  or ‘Mazhe pot bharale.’

In a similar way the sexual excitement and arousal keeps increasing every day. One fine day you have the privacy, so you get a chance to masturbate. You have some sexually stimulating material [SSM ex. pornography] to read or see. So, having masturbated once you are aroused again and you repeat masturbation. For example, you masturbate three more times. After that, it is enough and you fall off to sleep. You feel it is over. You are done.

Masturbation mimics sexual intercourse.

It is a natural and safe way of enjoying sex.

The person says that masturbation and sexual intercourse are different. One may think that masturbation is unnatural whereas sex is natural.

The argument they give is:

The penis is not meant to be rubbed in hand but is made for softer vaginal passage. Hence, because of mishandling, you are afraid that your hand practice, (colloquial for masturbation) has harmed your penis. You believe masturbation has caused damage to the blood vessels or nerves in the penis.

Therefore, he says, Doctor, “Sex mein alag hota hai. Haath se kiya isliye nuksan to hoga hee”.

(Translation)

That is, rubbing is not done in the vagina but is done using one’s hand. This is unnatural, whereas rubbing in the vagina is natural. Hence damage to penis or nerves or vessels [naas] ought to happen.

One’s own body part cannot and does not harm or hurt another part. Your hand cannot and does not keep pinching your ear because it pains. Even while shaving you do not allow to get cuts or wounds. Similarly, your hand cannot harm your penis.

Masturbation even when done in a prone position by rubbing on the bed. In this method of rubbing as well, there is no harm done to the penis.

It is the age when the mind is extra-sensitive about self-image.

One believes it causes weakness, backache, hair fall, and other troubles. Wrong beliefs about masturbation cause incessant worry and mental fatigue. This worry along with guilt results in psychosomatic illnesses.

Masturbation does never cause weakness or loss of energy.There is a ‘relaxed’ feeling after orgasm in both male and females. This is not ‘tiredness’.

Still, the fact that masturbation is harmless is difficult to digest for the majority. Over 80% of people, even educated people, even those who know that masturbation is healthy and harmless continue to fear that masturbation is not good; it is preferable to avoid it. This feeling is because wrong knowledge has been imprinted on their sensitive mind during early childhood. This stays for several years. There is mental programming of guilt and sin that needs to be changed with correct scientific knowledge. It needs to be reiterated that masturbation is healthy, harmless, and does not cause weakness.

Ignorant patients often say, “Semen is lost, thus valuable energy is lost”. Some people even believe that semen is limited and has to be rationed, not wasted. Some believe that one drop of semen is equivalent to one hundred drops of blood. He says, “Veerya / Dhat chala jata hai, takat chali jati hai”.

Translated: He says that one ejaculation of semen energy is lost.

The semen is energy or calorie-rich, is blatantly false. If you give the sample of your semen in a laboratory, the same place where blood and urine tests are done, you will find that semen has negligible energy if any. So even those who believe they have done excessive masturbation will not suffer from loss of energy.

Semen is not an energy reservoir. 

Nor making of semen or “refilling” requires energy.

Loss of semen either during masturbation or during sexual intercourse does not cause loss of energy.

MASTURBATION: SCIENTIFIC ANALOGY 1
Does loss of one ml of saliva lead to depletion of energy?
Dhat or Veerya or Semen is something that is meant to come out of the body and not to be preserved.

MASTURBATION: SCIENTIFIC LOGIC 2
A powerful logic is presented below:
When a patient is very weak and feeble you have heard the doctor saying that the patient requires blood infusion to restore strength. Therefore, you call friends and relatives to donate blood.
Have you ever heard the doctor saying, “The patient is weak so arrange for semen to infuse strength in him”? You’ve never heard that because seminal fluid has no strength in it. If there was vital energy in semen we would have used it to build strength. Either by swallowing or by using semen in some other form. Just like born-vita, semen-vita the energy would have been used. I imagine there would be semen pills to restore or build power, strength, and vigor for the weak as well as for the healthy.

There is nothing good or bad about masturbation. It is simply a desire for sex. If a partner is not available, the most innocent and safest way is to masturbate.

Masturbation in our socio-economic culture is considered a sinful act. But it is not true. Almost all have experienced it once or a couple of times. It’s only that, nobody talks in public about it.

Masturbation does not affect sexual performance nor affects the quality and quantity of sperms. The capacity of your becoming the father is not altered.

There is nothing like excessive masturbation.

The guy can perform the act as per his desire. There is an autostop to the process, wherein spite of trying to do so, one can’t.

Masturbation is normal and there is nothing wrong if one masturbates. 
(Do it in privacy, the way you bathe in privacy.)

If a young man says he has never masturbated, either he is lying 
or 
He needs to be investigated for the presence of masculinity.
