Men may have a variety of problems during sexual intercourse, and one of the most painful problems is “impotence”. There are many online consultation and consultation of men did not understand what impotence is, so it is necessary to teach you how to self-identify and diagnose “impotence”. 1. Suddenly, you don’t have a hard-on after a continuous battle. Even a healthy person can be out of shape at times! The same goes for the erection of the penis. It is normal for the penis to not be hard or to not get hard at all after several days of continuous sexual intercourse or several times a day of ejaculation, so there is no need to be anxious and nervous. Likewise, if you just recently a few days erection is not very good, there is no need to panic, to analyze your recent is not the existence of some of the following situations: fatigue caused by work, psychological stress, irregular diet and rest, excessive sadness, etc., these daily changes in work and life will have adverse effects on the physical condition, of course, erectile function will also suffer. 2, usually erection is very good when the key does not work. Some men usually have good erections when no one is around, or when they masturbate, but when the time comes, they are not hard enough or simply can’t get an erection. The reason for the poor erection is generally related to psychological factors. This situation is more common in young sexually inexperienced men, lack of sexual knowledge and too mysterious about sex life, fear of failure to have sex again to add to its psychological pressure, feel ashamed of the woman and so on bad psychological state is easy to make repeated failure of sexual intercourse. Some men will therefore gradually lose interest in sex and avoid sex. The woman’s dissatisfaction is more likely to make the impotence symptoms worse. 3, masturbation erection ejaculation normal, normal sexual intercourse weak, or even not ejaculate. It is certain that masturbation has no effect on health, but it is true that some men suffer from impotence and premature ejaculation because of masturbation. The penis must be stimulated with a certain intensity in order to get hard. As the hand stimulation is stronger, long-term frequent masturbation will make the penis adapt to this stronger stimulation pattern and thus lose its response to the weaker stimulation pattern of the vagina. 4, erections used to be fine, but now they are getting weaker and weaker. Some men were fine a few months or years ago, but recently they have been gradually failing, which is the case for most men with impotence. For example, the hardness of the erection has recently decreased, or penetration is difficult, or simply impossible, or even if penetration is successful but weak before ejaculation. Men who experience these symptoms need to be further examined for possible problems with the function of the blood vessels in the penis, such as possible lesions such as inadequate arterial supply, venous leaks and vascular malformations. Causes of abnormal vascular function include age, congenital factors, androgen deficiency, diabetes, high blood pressure, high blood lipids, etc. Therefore, it is necessary to do the corresponding examination. 5. Other conditions such as impotence after trauma and treatment of certain diseases. (1) The more common cases are impotence after taking certain drugs for a period of time, such as antihypertensive drugs, anti-psychotic depressants, and anti-androgen drugs, all of which have certain impotence side effects. (2) Impotence occurs after paraplegia due to spinal injury or pelvic fracture, the former is due to damage to the erectile nerve, the latter is due to damage to the vascular nerve, thus causing impotence. (3) Similarly, impotence after prostate cancer surgery and pelvic surgery is also caused by neurovascular damage; patients with abnormal penile erection after treatment will experience impotence due to damage to the cavernous body. 6. Seeming impotence is actually premature ejaculation. Some men ejaculate quickly or even before penile penetration, and the penis weakens after ejaculation. Thinking that this weakness is impotence.
