What is a penis?

The penis is actually the reproductive organ, the main organ during sexual behavior. Usually the penis is the mating organ of male animals. For humans, men should also pay attention to the care and health of the penis in their daily life to avoid being affected by various reproductive diseases.

The penis, also known as the penis, is a basic biomedical term that refers to the external reproductive organ of higher vertebrates. Like the female vagina, it also develops from the copulatory organ primordium in the embryo and is the main organ during sexual behavior. From the appearance, the penis is an oblong cone or oblong cylinder of varying thickness, and has two states: flaccid and erect. The penis is the mating organ of male animals. It is usually soft, and the glans is hidden in the foreskin; during mating, it becomes erect, elongated, thickened and hardened, and the glans is exposed. After thrusting into the female vagina, semen is ejaculated. The main functions are to discharge urine, discharge semen and mate.

Knowledge about the penis

1: Many people have a slight bend in their penis during erection, and the degree of bend varies from person to person. Some will bend upward or downward, and some will bend to the left or right. This is definitely not a supernatural power or a strange disease. As long as it does not cause discomfort or hinder your sexual activity, it is normal.

2: What standard do men usually use to measure their masculinity? Muscles, strength, or the length of the penis? The penises of Easterners and Westerners are almost the same, and are roughly about ten centimeters when erect. Sexual ability has nothing to do with the length of the penis, but is closely related to hardness and endurance, and the harmony and satisfaction of both parties. Some so-called "short and fine penises" look very strong, but they are actually useless, so remember "don't talk about others' shortcomings, don't show off your own strengths."

3: Sperm can be produced every day and can survive in the vagina or cervix for 72 hours.

Basic knowledge about the penis 4: The penis is mostly made up of corpus cavernosum, which is covered with a layer of epidermis. When sexually aroused, the corpus cavernosum becomes engorged with blood, causing the penis to become harder, longer, and thicker for sexual intercourse. This is called an "erection."

5: For some men, being able to erect for a longer time is their dream goal. Some people will also use the length of erection to compare. In fact, erecting for too long will make people unhappy, because the penis is erect for too long and does not subside. Not only will you not be able to enjoy the pleasure of sexual desire, but it will also make you feel miserable. Injections that treat impotence or leukemia can cause this.
