Usually, men only know that the penis will erect when it is sexually stimulated, as long as it is sufficient and firm enough. In fact, erections are graded, and foreign researchers call the most complete erection "first-class erection". Not all men can meet this standard. However, no matter how erect men are now, as long as they abide by the following principles and stick to it, they will certainly reach the standard of "first-class erection".

First: Never smoke.

A study by the University of Kentucky found that the average erectile status of male smokers was 5, while that of non-smokers was 9 (full mark 10). Urology experts at Boston University Medical Center said that harmful substances in cigarettes can cause blood vessel damage and make the corpus cavernosum lose elasticity. Another study found that the penis of smokers is significantly smaller than that of non-smokers.

Second: Never have a vasectomy.

If men have completed their reproductive mission, they can consider ligation. Contraceptive failure is an important reason for some men's anxiety. This will affect men's erection, further create a vicious circle of emotions, and eventually become a "temperament" killer.

Third: men should behave themselves and not be romantic.

After a short extramarital affair, it is likely to be accompanied by erectile dysfunction. In fact, many sexual medicine doctors often warn patients that "underground love" will induce guilt and anxiety, which will lead to ED (impotence). Therefore, if you want to maintain good sexual ability and have the highest erection state, men must not be romantic, so be careful!

Fourth: Sex should be slow and not too violent.

More than13 of ED men have suffered penis injury. In sex, "women are superior to men" and sex is too violent, which are all factors that threaten the penis.

Fifth, keep proper exercise every day.

Among those men who need to sit for a long time, those who walk 2 kilometers a day have a half chance of erectile problems, and jogging for 20 minutes or strength training for 30 minutes can achieve the same effect.

Sixth, you can yawn more.

Yawning can cause the brain to produce nitric oxide. It can not only reach the respiratory nerve and protect the cardiovascular system, but also reach the blood vessels that supply energy to the penis along the spinal cord. One of the functions of drugs used to treat erectile dysfunction is to promote the formation of nitric oxide in the body.

Seventh: Be sure to get enough sleep.

After entering a deep sleep state, the penis is in a long-term erection state for 3 to 5 hours. This is a way of self-maintenance, which can promote blood circulation. From a functional point of view, the more times a man has an erection at night, the better the flexibility of his sexual life. This can ensure that men have a stronger erection during sexual intercourse.

Eighth: Use healthy sex toys.

I must tell you that modern high-end sex toys are a good helper for men to maintain their erection strength.
