In many people’s view, the penis should be the Monkey King’s “like a golden rod”, with the time immediately “hard as iron”, not when immediately “soft as cotton”, as long as there is not as good as once, a “impotence” hat on himself. A “impotence” hat on their own. The World Health Organization defines impotence as: erectile dysfunction is defined as the persistent inability of the penis to achieve and maintain an erection sufficient for satisfactory sexual intercourse for the past three months. In other words, it takes more than 3 months of persistent poor erection and inability to have sex to be diagnosed as impotence. As the main initiator of sexual life, men, unlike women, are able to have sex even when they have no sexual desire. As a matter of fact, men’s sexual function is very fragile. Exhaustion, stress, mood swings, physical discomfort, and even a disgruntled look from a woman can lead to failure in sexual intercourse. Therefore, men should not take the success or failure of the hero, do not arbitrarily find themselves a “impotence” hat to wear, to have a “repeated defeat” spirit, to have a certain success of self-confidence. Accurately speaking, the man is not a sex life, is “self-confidence”.
