In the male sexual physiology, most male compatriots are very concerned about whether their penis is up to standard, and many even believe that the size of the penis is related to the relationship with the other half of good or bad. This concept is wrong. Basically, the shape, size, and length of each male genitalia are not the same, and these size and length factors are not directly related to a man’s sexual desire, sexual ability, and sexual attractiveness. determine the hardness of the penis during erection. Hardness is the most essential element for men during sex, and if the penis is not hard, what happens next will be difficult. In sexual medicine, the hardness of the male sex organ is much more important than the length, so you can often hear about conditions such as impotence and inactivity, but rarely hear about the problem of a penis that is too long or too short. “The reason Viagra became a hit was because it solved the problem of hardness and had nothing to do with length. To maintain the hardness of the penis, the main key in terms of physiological factors is to keep the erection of the penis congested, that is, the spongy body of the penis allows more blood to enter and less to flow out. Psychologically, worry, apprehension, fear, distraction… etc. can also affect how hard the penis is when it is erect. Many men have problems with intercourse mostly on a psychological level, but mistakenly believe that it is related to length or other physical factors. If it’s a physical problem, you should see a doctor; if it’s psychological, then you should see a psychologist.
