What is the picture of a man's erection?

When a boy gets an erection, his penis will change a little, but many people don't know what he looks like when he gets an erection, because every man's sex organs are different. When he gets an erection, his state is naturally different. So, what is a man's erection like? What's it like to be under a boy? Below, let's learn about male erections with us.

Three elements of maintaining erectile function

1, appropriate stimulation

2. Nerve function is normal

3. Adequate blood supply

Men usually have four erectile states.

Male genital erection looks the same, but the principle is different. Psychological activity, mechanical stimulation and the release of brain inhibition may all make people erect. After scientific research, men's genitals usually have four erectile States, which are related to sexual health.

① Psychological erection

When men are excited by sexual stimuli such as hearing, sight, smell, thinking, imagination, etc., it will spread through the erection center of thoracolumbar spinal cord and act on Tintin cavernous body, which will dilate arterial blood vessels and flow a lot of blood into Tintin cavernous body; When the venous blood vessels contract and the blood flowing out of the cavernous body decreases, the blood will fully stay in the rich blood vessels and blood sinuses in the cavernous body, which will make Tintin have a psychological erection quickly. On the contrary, when arterial blood vessels contract, the blood flowing into Tintin's cavernous body decreases; When the venous blood vessels dilate and the rich blood flow trapped in the cavernous body quickly returns, Tintin will recover from weakness.

② Reflex erection

When the external genitalia is stimulated by direct touch, walking friction and other local stimuli, or by internal stimuli such as rectum and bladder, it can cause reflex erection, which is achieved by stimulating the erectile center at the lower part of sacral pulp in the spinal cord to cause sexual excitement.

Tintin's erection is natural, and male fetuses can also erect in the womb. When a little boy urinates after birth, he may also have an erection and become hard. Sometimes lying there to urinate can make urine spray straight on adults' faces like spring water, which often brings unexpected laughter and joy to parents who are changing diapers, but erection at this time has no sexual significance.

Any stimulation of genitalia itself can cause reflex erection, which plays a regulatory role through female private nerve and sacral spinal erection center. These two kinds of psychological and physiological stimuli can not only act independently, but also influence each other and participate in sexual activities.

For example, when spinal cord injury occurs above the thoracolumbar region, the patient can only erect when the genitals are physically stimulated, and the ability of psychological erection disappears. When motor neuron injury occurs below the thoracolumbar level, genital stimulation can not cause erection, but 24 ~ 57% patients still have psychological erection, that is to say, psychological stimulation can be transmitted through the thoracolumbar channel. When spinal cord injury occurs at waist 2 ~ sacrum 1, both psychological and reflex erections exist, but they can't be coordinated, so it is impossible to reach ejaculation climax through genital stimulation.

③ Erection at night

In addition to psychological erection and reflex erection, normal men also have a nocturnal erection. Men's sleep is always in the alternation of rapid eye movement sleep and slow eye movement sleep, and they also experience the physiological process of erection-weakness-re-erection-re-weakness, which is medically called Tintin's nocturnal erection, which is a normal physiological process of healthy men. Generally speaking, men have erections for 20 to 40 minutes four to six times a night, and the total erection time can reach two and a half hours. This is because the brain always inhibits the occurrence of daytime sexual reactions, otherwise men will inevitably encounter embarrassing situations from time to time. However, after deep sleep, this inhibitory function of the brain disappeared, and Tintin spontaneously produced an erection reaction. This is completely normal, don't worry.

The time, frequency and hardness of nocturnal erection will decrease with age, and it will be the strongest from adolescence to 20 years old. Whether it is psychological or reflex erection, Tintin will soon return to normal after the external stimulus is lifted. Erection at night is no exception. Tintin's erection will certainly weaken automatically after a period of time, because if the blood stays in the cavernous body for a long time, the blood will lack oxygen and accumulate a lot of metabolic waste, which is not good for the tissue, and even necrosis will occur in severe cases.

Tintin has an erectile dysfunction. The patient's symptoms are persistent swelling, hardness, pain and bluish-gray tintin for more than 4 to 6 hours. This is an emergency in urology, and we need to go to the hospital for emergency treatment as soon as possible. Therefore, Tintin didn't get an erection all night, but he must relax.

④ Erection in the morning

Erection in the morning is a meaningful physiological phenomenon in clinic. Some doctors have specially studied this phenomenon and found that men's erections will weaken or disappear in the morning during their illness; After the body recovers, the erection in the morning will also recover. Therefore, early morning erection can be used as a reference index for men's health. Erection in the morning can also be used as a reference index to judge male sexual function.

The size and length of a man's tintin are related.

1. The average length of erect tintin is13.12cm.

2. The average body length of weak Tintin is 9. 16 cm.

3. Straighten weak tintin, with an average of 13.24 cm.

4. During erection, the average girth of Tintin was 1 1.66 cm.

5. When in a weak state, the average circumference of Tintin is 9.3 1 cm ... See details.
