Erectile dysfunction, also known as ED, is one of the most common male dysfunction diseases. There are many kinds of causes, but in general, they can be divided into three types, namely, diseased reason (organic), functional (psychological), and drug. Those with serious illness are commonly referred to as "impotence".
According to a survey, the average length of Chinese men's penis after erection is 13.4 cm, far exceeding the need to meet women's sexual needs. So: hardness is the most important!
Which factors are the most important in sexual life. The results show that the first is the hardness of erection, and the second is the duration of erection. The ratio of the two should be about 50% and 30%.
Research shows that hardness is the most basic factor in men's sexual life. If the penis does not harden, it is mainly because of the penile blood vessels. If the blood vessels are not congested enough, the hardness is not enough. If the blood vessels are not congested enough, it is because of the vascular endothelial cell problem, the muscle problem in the blood vessels, and the problem of the mind. Insufficient hardness is the first problem in erectile dysfunction. Without hardness, you cannot insert.
The first level is the worst, the penis has hyperemia and enlargement, but cannot erect and insert;
Level 2 is slightly better, with slight erection, but still unable to insert;
The third level can be inserted, but it is still not strong enough. It belongs to "Microsoft", or half of it is soft and cannot last;
Level 4 is the best. It is completely erect and firm, and can last.
