What does a man consume during sex?

A healthy male ejaculates about 5 ml of semen per ejaculation.

Modern medical analysis of semen has found that there are about 200 million sperm living in these few milliliters of semen. The results of biochemical analysis show that 98% of semen is water, the remaining about 2% is protein and RNA, and there are very small trace elements such as zinc. Once these figures come out, we will find that what men lose in one-time life is really insignificant. For example, the nutrients lost from ejaculating once and spitting out saliva are almost equal. I have never heard that spitting out saliva will cause "kidney deficiency" or the need for "tonic therapy".

Sexual activity consumes energy

In this age where "life is movement", this statement is particularly ridiculous. Some people who are very serious about things have also done experiments and found that a passionate sex life consumes about the same amount of calories as riding a bicycle at a moderate speed for one kilometer (about the distance of two bus stops). It is estimated that tens of millions of men on this planet "expend their energy" every day on two wheels of a bicycle, believing that this does not in any way harm their health and may in fact increase their physical and mental vitality.

I have met many men who have seen Chinese medicine doctors, and all of them have been labeled as suffering from "kidney deficiency"; I have also seen many people who "replenish the kidney" because of "kidney deficiency", but I have never heard anyone say that the "kidney" has been replenished to the point of no longer being "deficient". For men who believe in simple materialism, kidney tonification is probably a lifelong career. This is truly an invisible shackle on the spirit of Chinese men, which can restrict the freedom of mind and body more effectively than visible shackles.
