To take a glass of wine or beer once in a while, is not a problem. Someone in that experience will not need to know “Dry January.” Those who are lost in alcohol, will surely experience what “Dry January” is. An extreme brings another.
Same principle applies with sexuality and celibacy.

For most individuals, sex has 2 main functions: Reproduction and fun\pleasure. There are more functions in sexuality, only known/experienced by few.
Most men are unaware that their vitality is embodied in their semen. The importance of this vital energy will be seen as the individual ages.
Most individuals are incapable of regulating their excitement and need to ejaculate. Due to the “macho”/”stud” conditioning, many men are depleted of their sexual energy, then; when they reach their 40-50- 60s they lack vitality.
What was the solution for this problem?
Nowadays, it is a “blue pill” which will take the person into further depletion or in other terms: it will submerge the person into greater vitality debt.
Before the “blue pill,” there was the natural means: Celibacy.

It was thought that by “not doing it,” a person will lose interest. Religions tried to sublimate the sexual urge by “purifying” a relationship through love of God or condemning sexuality and the “pleasures of the flesh.”
However, there cannot be celibacy when the individual is repressing and denying his own sexuality.

Celibacy is not repression. However, celibacy could be used as medicine to restore the vitality of an individual. When an individual is running in deficit, celibacy is not a repression, but a needed “practice.”
Some individuals believe that celibacy is only to abstain from sexual relationship with another; however, it is as well to abstain sex with yourself.

Nevertheless, the important factor is for the man to maintain its semen as much as possible, and not to abstain from human touch, feelings and pleasure.

It is easier to maintain a “black or white” posture: No sex, no touch, no pleasure and to disseminate the message that this “practice” is “spiritual.” However, most; at least 99% of individuals will repress to comply with this “spirituality.”

Since the above may be too restrictive; sex, touch and pleasure were allowed by some religious/ spiritual systems; but not ejaculation at all.
What was the outcome? Utter pressure. Sex was no longer enjoyable as someone has to “watch” for the moment of “no return.” Then guilt sets in, for that “failure” and the consequences of it.

The “reality” of human sexuality is that we cannot put all human beings in the same basket. We are all different and those differences will change in time: A 60-year-old is very different than a 20-year-old. A society will teach them to comply with some belief or some moral ideal, but the teaching does not cover to be AWARE of ourselves.

If a human was AWARE of himself, he will know to walk the “middle way” and to put himself in that path as Life turns into different streets. That “middle way” is never the same; nevertheless; it is the natural way. Most are prey of social/peer pressure, collective beliefs and nonsensical traditions which endanger their own well-being. That is the path of extremes.

Celibacy is as good and necessary as Sex is. They can complement each other. It all depends in timing, setting and circumstances.  The keyword is “Balance.” To “practice celibacy” means for a limited time. Typically, we don’t “practice” sex.  Naturally, we ARE sexual beings, but according to who WE ARE, we could manifest love and care through sex, OR lust and violence.
When celibacy is natural, it is no longer celibacy. Anything “practiced” with repression, will NEVER be natural.
Semen is Life. Through that we give Life to another. Your Life, your vitality depends on keeping that energy.

How many times a month shall I ejaculate?
You are missing the point. Discover what works for you. Be sensible, aware of what your body tells you. Change when there is a need.  Forget about the “scientific research,” of what should be “normal.” Feel the balance. What is natural does not rely on numbers and formulas.
Sex and celibacy are the complete human sexual experience. They are ONE.
