Men often peer at the size of other people’s penises in bathrooms, public baths and some other places. When he sees that other people’s penises are smaller than his own, it gives him a moment of relief and pleasure. But it’s often only for a moment, and it won’t be long before he’s lost again! A bigger penis will come into his view and a recurring thought comes to mind: “It would be nice to have a longer one ……” Don’t be surprised, men always want that. The fragility of the male sexual psyche seems to be beyond our imagination. When we were kids, we would compete with each other to see who could pee farther and who could pee more fancy! But once you reach adulthood, few men will talk about these topics with their friends. How big is a normal penis? This is a question that confuses many men! But few people will ask it! There is a story: once someone asked U.S. President Abraham Lincoln: How long should a man’s legs be? After thinking for a while, Lincoln replied: “I think they should be about long enough to reach the ground from the body.” In terms of reproductive needs, a normal penis is long enough to enter the vagina, and offspring can continue as long as sperm is ejaculated into the vagina without overflowing. Because penis size is an inherited trait from generation to generation, a penis that is too short to enter the vagina will have difficulty in sowing the next generation. In fact, races with short penises would have been extinct half a million years ago. In terms of satisfying women, penis size (whether length, diameter, or some other measure) has nothing to do with the ability to cause orgasm in women. Sexual stimulation during a woman’s orgasm is focused on easily accessible sexual organs, such as the clitoris, labia and surrounding erogenous zones, which include the outer third of the vagina and can be easily reached by any adult penis. Sexual intercourse and artistic creation is generally more about quality than weight. What is certain is that men need a bigger penis, neither for procreation nor to satisfy their spouse, but to satisfy themselves and give them more confidence and pride. And this seems somewhat absurd and impractical. This leads some to boldly say that the real reason for male modesty is simply that each man wants to hide what he considers to be a too-small penis. Perhaps there is some truth to this view. It is true that some people have measured how big the human penis really is. The average erect penis length for the average Han Chinese male is between 10-11 cm. In the clinic, it is extremely rare that we see a penis smaller than this length. So often at the end of the physical exam, we sometimes give a compliment to those who are worried that their penis is too small: “That’s the nicest penis I’ve seen in the last two days”
