Why do men get hard?

Sex education is no longer a topic that everyone avoids talking about, because there are many ways for minors to get in touch with sex education, such as television, movies, mobile phones and various network devices. Instead of letting them secretly check it out, it is better to spread scientific sex knowledge in the classroom. Just like girls are interested in their breasts, menstruation and other physiological issues. Men are also interested in their sexual organs. So why do men get hard down there?

The penis, also known as the penis, is the male reproductive organ. It is a basic biomedical term that refers to the external reproductive organs 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. In terms of 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, with the glans hidden in the foreskin; it becomes erect during mating and the glans is exposed. Sperm is ejaculated after sexual intercourse in the female vagina. Its main functions are to discharge urine, discharge semen and perform mating.

Basic knowledge about 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.

4: The penis is mostly made up of corpora cavernosa, which is covered with a layer of epidermis. When sexually aroused, the corpora cavernosa become engorged with blood, causing the penis to become hard, longer, and thicker for sexual intercourse. This is called an "erection."

There are several reasons for "erection":

Reason 1: It is a completely normal physiological phenomenon for boys to have an erection. It is not a disease, nor is it something shameful. It is just that adolescent boys are particularly sensitive to sexual stimulation due to the increased level of androgen.

Reason 2: Getting hard in the morning is a common physiological phenomenon for men with normal sexual function. It is not dirty or obscene. The hardening of the penis is also related to the transfer of personal willpower. Relying solely on "noble" thoughts will be of no avail. This is also the reason why boys get hard down there.

Reason three: If men read too many articles about sex scenes in their daily lives, their sexual central nervous system will often be in an excited state, so they will easily get hard when they are slightly stimulated. Also, tight underwear, heavy blankets, smegma deposits, balanitis, and diseases that stimulate the nerve endings in the urethra and spermatic collaterals can easily induce hardness. This is an important reason why boys get hard down there.

In daily life, if your penis becomes hard during intercourse, it is very bad. In daily life, you should not wear tight underwear and read too many sexual articles, so as to prevent the situation of frequent hardness.
