You don't understand how addiction works. Yes, it's not the same as eating and sleeping. But it's also not the same as your average person who just loves sex. Sex addiction is a real thing.
But I am simply saying that sex, eating, sleeping and self-preservation are the four primitive urges shared by every human and every animal. They are biological necessities.
Drugs, gambling, shopping, et cetera are not biological necessities. You can give those up cold turkey and still survive biologically. They have their origin in the mind.
Sex, food, sleep and self-preservation if not given a physical outlet will cause the physical organism to cease or become crippled. Also, to not allow one or the other of sex, food, sleep, self-preservation to have expression, causes the other urges to become more active.
For instance, sleep deprived could cause an over-load on self-preservation or eating more or even more sex as you are denied the equilibrium of sleep. Many people who have eliminated sex, over-eat. Sex is the least important of the 4 primitive urges because it can be sublimated by masturbation or sickness or disease can deplete its function. If a young healthy strong boy or man is producing semen and does not allow outlet, his behavior becomes violent and also the prostate becomes enlarged and causes great pain.
Age usually depletes the insatiable sex drive that men have in youth. But that desire that is not allowed expression through the body remains in the conscious and subconscious mind and disturbs clarity of mind. One might act out in other ways that are considered perverted or put an overload on sleep, food and self-preservation or turn to drugs to appease that unsatisfied urge.
I had a girlfriend who had a male dog that she neutered. When her and I engaged is sex, the dog used to watch and try to imitate us by humping the couch. the dog was not erect because his organs were destroyed but the urge still remained in the mind of the dog as he tried to perform the action that nature provided.
Catholic priests are denied sex with women so they seek out altar boys and probably each other.
Sex is the primal urge that put you here on earth. Do you think that mother nature will allow you to forget that basic instinct?
Taoist and tantra yoga experts like Mantak Chia give discourses on ancient practices where the semen produced by men is internally boiled by vigorous yogic practice and breathing and the semen bypasses the penis outlet and the essence of the semen travels up the spine to the brain and then showers down through the nervous system allowing the yogi to experience a high level of bliss. And there are other practices like this used in the Himalayan cave monasteries where men consciously give up sex and they sublimate in this fashion and not through masturbation because they believe the loss of sexual vitality through sex and masturbation robs them of their life-force that could be used to focus on higher levels of spiritual pursuits that produce pleasures higher than mere ejaculation. But, of course these practices are not ordinarily understood and practiced by us as they take time and patience to cultivate. It was common amongst Shaolin monks and gong-fu and qi-gong masters.
Experiment on yourself if you are sexually active and deny yourself sex and masturbation for a month and monitor your behavior and you will have first hand knowledge of its power. You will change completely.
You will have to give up this forum and porn and you will have to discard sex from your mind each time a thought emerges. You will have to relinquish sexual thoughts because if you don't, the next thing you know, you will be grabbing your penis to engage it.
