Human sexual activity is a complex process. There are both psychological expectations as well as physiological responses and physical actions, and problems with any of the psychological and physiological components can occur and affect sexual life. Psychological factors are a very common cause of impotence, and the psychological factors faced by different men are often different. For example, men and women living together for a long time gradually develop what is called aesthetic fatigue, incompatible relationships with their spouses, and conflicts that often affect sexual desire and erectile function of the penis. For men who have just started their sexual life, sometimes the lack of sexual knowledge, or excessive mystery about sexual life, or excessive introverts, etc., can cause the penis to have an erection that is not hard or cannot be erected. Other causes of bad sex psychology include bad sexual experiences, irregular life, fatigue, work or financial stress, incorrect understanding of media propaganda, anxiety and depression due to fear of diseases and side effects of prescription drugs, etc. At the same time, anxiety and incorrect understanding of impotence can in turn cause psychological problems, the latter adding to impotence. Of course, psychological problems are only one of the important causes of impotence. It is important not to simply divide the causes of impotence into psychological and organic, because most of the causes of impotence are not single, both psychological and organic factors exist. Various diseases that affect vascular and neurological function can cause impotence. Examples include obesity, blood disorders, diabetes, hypertension, atherosclerosis, spinal and pelvic disorders or trauma, sex hormone deficiency, etc.
