How much energy does a man expend during one instance of sexual intercourse?

A healthy male ejaculates about five milliliters of semen at one time. Modern medicine's analysis of semen has discovered that in these few milliliters of semen, there are approximately two hundred million living sperm. The results of biochemical analysis show that 98% of semen is water, the remaining 2% is protein and ribonucleic acid, and there are also trace amounts of microelements such as zinc.

When we see these numbers, we will find that what a man loses during one sexual activity is truly insignificant. To give an example, the nutrition lost from one ejaculation is almost equal to that lost from spitting out one mouthful of saliva. We have never heard of anyone experiencing "kidney deficiency" or needing "nourishment" from spitting out one mouthful of saliva.

Some people talk about the harm of sexual activity to men from another perspective, saying that sexual activity consumes physical strength. In this era that advocates "life is movement", this statement seems especially absurd and ridiculous. There are also some people who like to be meticulous and have done experiments, finding that the calories consumed during one passionate sexual activity are roughly equivalent to those consumed while cycling at a medium speed for one kilometer, which is about the distance of two bus stops. On this planet, it is estimated that millions of men sit on bicycles every day "consuming physical strength". Believe that this has not caused any harm to their health; in fact, it may have increased their physical and mental vitality instead.

Why do you feel tired after making love? Since sexual activity is a kind of "activity", it requires energy support, which is beyond doubt. Just like dancing, walking, and swimming, it consumes a certain amount of energy and physical strength. Sexual scientists point out that an average middle-aged man has sexual intercourse twice a week, and each time from the start of sexual stimulation to reaching sexual climax, it takes an average of 16.3 minutes. Actually, from the mutual contact of reproductive organs to reaching sexual climax, it only takes about ten minutes.

According to the above statistics, a middle-aged man spends only 0.3% of his weekly time on sexual activities. The energy consumed by exercise is determined by the duration and intensity of work. The time of sexual climax is very short, and the entire sexual activity process only lasts 10-15 minutes, so sexual activity is an activity that takes up little time, uses moderate force, and is not excessive. Therefore, sexual activity does not consume huge physical strength or too much energy. Aviation medical experts conducted comparative studies on pilots. The quantity and quality of tasks completed by pilots who spent the night with their wives at home and those who spent the night alone at the airport were consistent.

Of course, it should be pointed out that a minority of men indulge excessively in sex, with overly high frequency of sexual intercourse, and some even engage in uncontrolled extramarital sexual activities. This is extremely harmful and should be restrained promptly, maintaining self-respect and self-love.

Therefore, indulging excessively in sex leads to sexual fatigue.

I have seen many men who have seen traditional Chinese medicine doctors, all of whom were labeled with the "kidney deficiency" hat; I have also seen many people who "nourish their kidneys" due to "kidney deficiency", but I have never heard anyone say that their "kidneys" are no longer "deficient" after nourishment. For those men who believe in simple materialism, nourishing the kidneys is probably a lifelong endeavor. This is indeed an invisible shackle on the spirit of Chinese men, more effectively restricting the freedom of mind and body than tangible shackles.
