The glans penis is not hard after erection

During intercourse or when there is an urge to have intercourse, the male penis will become hard so that the intercourse process can be completed satisfactorily. However, many male friends will find that the glans penis is not hard when the penis is erect, which will cause inexplicable anxiety in their hearts. So why is the glans penis not hard when it is erect? Is this impotence? The following will explain this problem from the structure of the glans penis and the mechanism of erection, as well as the changes of the glans penis during the erection process.

1. The structure of the glans penis

The male genitals are mainly composed of three parallel cylindrical corpora cavernosa. There are two corpora cavernosa and one corpora urethra. The three corpora cavernosa have different structural types. The figure is a cross-sectional view of the male genitals. If you stand up, the genitals are erected at a 90-degree angle to the human body, and the positions and structures of the three corpora cavernosa are located on both sides of the upper end of the male genitals, and the corpora urethra is located below the corpora cavernosa.

Let's talk about the corpus cavernosum first. The corpus cavernosum looks like a "carrot". The section outside the human body is relatively thick, while the thin and pointed end is in the shallow layer of the human body, also called the male genital crus. The thin and pointed end (male genital crus) is connected to the skeleton by a cruciate ligament, such as the often mentioned male genital suspension cruciate ligament. The cruciate ligament mainly plays a role in fixing, fixing the corpus cavernosum of the penis firmly on the skeleton, so that the male genitals will not move during erection and sexual intercourse. The thick end is connected to the glans penis below, mainly to support the glans penis (glans penis).

The corpus cavernosum is located just below the two corpora cavernosa and is known for the fact that the urethra passes through it. It is much smaller than the corpora cavernosa. The corpus cavernosum is located outside the body and expands to form the glans penis. The glans penis tissue is very dense and wear-resistant, making it easy to have sex. The inner part of the corpus cavernosum is connected to the prostate of the urethra.

2. Different physiological changes of the glans penis during genital erection

During sexual desire or intercourse, the male genitals will become hard and erect, but the functions of the corpora cavernosa and corpora cavernosa are different. The corpora cavernosa of the male genitals will continue to increase with blood, and its strength will increase, and its compressive strength will be close to that of cartilage (or forehead). The corpora cavernosa of the urethra will also swell and increase in volume, but the corpora cavernosa of the urethra and the glans penis are different from the corpora cavernosa.

In the above article on the structure of the glans penis, it is mentioned that the corpus cavernosum and the corpus cavernosum of the urethra are different in structure type, and it is this difference that ultimately makes them have different roles and effects in the process of penis erection. The outer layer of the corpus cavernosum is surrounded by a layer of tough tissue called the tunica albuginea, and the core is the ⬆ honeycomb sinus. The tunica albuginea is very tough and can hardly expand. The sinus can ensure that the pressure inside the corpus cavernosum of the penis is maintained at a relatively high level when the penis is erect. As a result, the corpus cavernosum can maintain good strength during penis erection. The corpus cavernosum of the urethra (including the glans penis) does not have a tough tunica albuginea and honeycomb sinus, so although it is swollen when erect, it is not easy to be very hard.

3. The different strengths of the male genitals and the glans penis during erection and their practical significance

From the above analysis, we can see that even for ordinary people, the strength of the penis and glans penis during erection will not be the same. The penis will become hard, while the corpus cavernosum and glans penis will only swell and swell instead of being hard, which is a normal state. From a physiological point of view, this is also in line with physiological needs. First, the hardening of the penis during erection can ensure that it can be inserted during intercourse, which is essential for couples' life. Second, the glans penis should remain swollen instead of being hard as cartilage during intercourse, which is also conducive to the development of intercourse, and can maintain comfort and avoid damage. Third, when the penis is erect, the corpus cavernosum of the urethra is only swollen due to blood, and the gas pressure of the corpus cavernosum of the penis does not increase significantly, so the urethra opening can be kept smooth. Only in this way can the semen be ejected from the urethra opening.

4. What is the strength of the glans penis when it is fully erect?

Generally speaking, when the penis is erect, the glans penis will swell and swell, and the strength of the glans penis is not the same as the strength of the penis body. When erect, the strength of the glans penis is only swollen and elastic. If it is normal for the penis body to be as hard as the forehead, then it is normal for the strength of the glans penis to be as hard as the "nose tip".
