Modern medicine has given a concise definition of impotence: it is a kind of penile erectile disorder, which usually refers to the inability of the penis to get an erection or a weak erection, a short erection and a quick flaccid erection in the presence of sexual stimulation and desire, so that sexual intercourse cannot be performed and completed. In fact, this definition requires the following points: first, this sexual stimulation must be from the spouse’s full sexual stimulation; second, should really be judged by the ability to complete sexual intercourse; third, must be after the marriage between the couple at least 2 to 3 months of friction, with the practical experience of sexual life before making an estimate; fourth, any extramarital sex can bring bias to the judgment. If you deviate from these principles, it is easy to have a misunderstanding of self-judgment and put on the hat of impotence to yourself, and from then on put on the mental shackles and one does not feel good. It is easy to fall into the following misconceptions when self-judging impotence: 1. The first few failed sexual intercourse after marriage as impotence. This situation is quite common, in fact, is contrary to the principle that there must be a 2 to 3 month bonding period after the start of sexual life between spouses. The new marriage, especially the wedding night, too excited, tired, or even drunk; or because of the lack of cooperation between the newlywed couple, caused by a moment of poor erectile function. Originally, this is not surprising. There are also individual newlyweds who have poor intercourse, is due to the forbidden fruit before marriage, then in the groping, trying, nervous, scared and other complex feelings act, the failure rate is high, so in the mind left their sexual ability is not good shadow. This situation, more should have a stage of adaptation in the post-marital intercourse. 2, the inability to cause the female partner erotic orgasm and pleasure as impotence. This is a bigger mistake, as long as the male penis can be erected and placed, as long as the male can successfully complete ejaculation through the action of sexual intercourse and reach orgasm, it is not impotence, even if the woman does not have sexual pleasure. One of the characteristics of male and female function is that “men are fast and women are slow”, so if the man has ejaculated, the woman has not yet entered the orgasm, this is a physiological phenomenon, at most the sexual life is not harmonious enough, should never be considered impotence. 3, think that masturbation will certainly cause impotence. This is a common mistake in sexual awareness among unmarried young people. It is no secret that masturbation is a common behavior among teenagers, and there are indeed some people who worry that masturbation will induce impotence, and then there are really people who have impotence. In fact, masturbators are very complex psychological activities, often in anxiety, guilt, depression, anxiety, such unhealthy thinking activities can prevent the normal performance of sexual function. However, even a long-term masturbator, as long as the above-mentioned mental “pimples” can be lifted, impotence may not occur. 4, the usual penile erection response is not obvious as impotence. A lot of teenagers have complained that their penis would naturally get erect when they watched certain movies and books with pornographic content; when they thought about a girl they liked; or when they indulged in some sexual fantasy, but now this reaction is not obvious, is it impotence? Wrong! The answer is simple, because there is no complete sexual stimulation from the spouse, including visual, audio, touch, smell and other aspects of sexual stimulation, but also because there is no real practice of sexual intercourse, based on the penis erection alone or not, can not make a diagnosis of impotence. In fact, there are two kinds of penile erection from the physiological point of view: one is reactive erection, without any sexual stimulation, through the nerve reflex spontaneous erection, such as the erection after sleeping at night is so; the other is mental erection, need some kind of sexual stimulation induced, including the unveiled from the mind about the sexual fantasy. Therefore, all erotic stimuli can induce a mental erection. This kind of mental erection occurs in the usual pattern is very mixed, will vary with a person’s physique, thoughts, emotions, etc., sometimes better, sometimes worse, this is not at all an indicator of impotence. 5, after the object of sexual intercourse changes the erection is not good that is impotence. Strictly speaking, this view is also incorrect. Some people have a normal sex life with their wives and have good erectile function; but in extramarital relationships sexual intercourse is a pout. On the contrary, there are people who have sex with their wives, perhaps out of the lack of novelty, poor erection occurs, but in the affair room is very good. These are the situation after the change of the object of sexual intercourse, at first glance, in with a certain object of sexual intercourse occurred erection is not good, is indeed a kind of impotence, medical also has the so-called “affair impotence”, “intra-marital impotence” method of speaking. But in the real sense, a person who has this “selective” impotence is not a real impotent person. On the one hand, he is impotent, but on the other hand, he has good sexual function. This shows that you can’t just put the label of impotence on this type of person. Of course, correcting the style, adjusting the mentality, and ensuring that the marital intercourse is normal is vital. 6, frequent seminal emission is bound to cause impotence. This is another fallacious viewpoint that teenagers often have. The actual fact is that frequent ejaculation hurts “vitality” and sexual function will be lost with it. In fact, this concern is completely superfluous, healthy unmarried men monthly ejaculation 1-2 times is normal, more than 4-5 times is more, which may be related to genitourinary organs inflammation or some life factors induced, such as wearing tight pants, sleep at night local too hot, overworked during the day, etc.. However, modern medicine has made it clear that there is no necessary connection between seminal emission and impotence. 7. Premature ejaculation will inevitably evolve into impotence later on. Those who hold this view can cite some specific examples of patients who started to show premature ejaculation and ejaculation without contact or shortly after contacting the female partner, and later even erectile function failed. From a medical point of view, such a situation is often still a case of psychological factors at work. As a result of premature ejaculation, they feel unsatisfied, ashamed of their wives and feel very guilty. Some wives reveal their dissatisfaction, ridicule and complain, which invariably gives the husband a huge pressure. Sexual function can really be washed away under this complicated psychological state and mental pressure. If they are effectively treated at the stage of premature ejaculation, if they are strong-willed and have an indifferent attitude, or if their wives do not mind at all, they will not become impotent. Today, modern medicine has not found a definite link between premature ejaculation and impotence. In conclusion, the diagnosis of impotence can only be clarified through detailed knowledge of the condition and rigorous testing. Any subjective guess or conjecture is not scientific.
