What is the shape and structure of men's sexual organs? How does the body react when the sexual organ is excited

Men (including many women) appreciate the straight, dry and beautiful mushroom head of the penis. Why is the penis like this? People may not know. From the perspective of evolution, make fun of it.

Foreign countries have read dozens of seemingly strange academic articles on evolution and analyzed why human penis grows into such a special problem. The result is strange, that is, humans generally have neuroticism, and the purpose of this shape is to maintain the purity of offspring DNA.

The penis is really a very special tool, especially the large glans formed by natural selection and the umbrella-like coronal margin, which looks very beautiful. According to the theory of evolution, the sexual relationship of human ancestors is complex and chaotic. After a long time of natural selection, we practiced this special shape, which is subject to its function. This special function is also very interesting, which helps to scrape off the semen previously arranged by others, make their own sperm play the role of fertilization alone, and ensure the purity of their offspring DNA.

From a theoretical point of view, the intensity and depth of the penis twitching in the vaginal tube can more effectively remove other people's sperm. The size of the penis is really important, not only for women's sexual satisfaction, but also for men. Evidence shows that this intensity will be more intense when the two sides meet again after a period of separation.

Why? It turned out that it was not easy for ancient ancestors to monitor women's behavior during hunting. At this time, women are easy to accept other people's semen. Therefore, the reason why a farewell wins a wedding is to quickly remove other people's semen. Of course, these behaviors were not conscious, and there was no scientific knowledge at that time, which was completely from the instinctive neurotic needs.

This is the natural response of human beings in thousands of years. The stronger the arousal, the stronger the ejaculation, the deeper the semen reaches the vagina, and the more difficult it is for other latecomers to remove semen. Once ejaculation occurs, the male penis will soon be tired, and further stimulation will bring different degrees of discomfort. This is also important. Because continuous twitching will bring out your own semen, which is not conducive to cultivating your own offspring.

Everything has a causal relationship. History is history, and reality is reality. We can never use the real life here. As I said in the past, size is not important, and time is not important. It is important to use it.
