Premature ejaculation is the most common male sexual dysfunction, with an incidence of about 30% in the population. Many people say that sex time is too short, how fast is too fast? How to determine it? There are various definitions of premature ejaculation, and the one recognized by most experts is: ejaculation before or within 1 minute after penile insertion into the vagina, reduced ejaculatory control, and adverse psychological and emotional effects on both parties. According to foreign surveys, the ejaculatory latency (from insertion to ejaculation) of most normal people is 7-13 minutes. Causes of premature ejaculation The real causes of premature ejaculation are still a difficult mystery, including a large number of studies and researches from physiology, psychology, behavior and even social and cultural background. There are some arguments that premature ejaculation is a problem on a purely psychological level, as men’s early sexual experiences (including masturbation) are often done under the tension of fear of being discovered, and a pattern of fast-action sexual behavior develops, which is difficult to change in later sexual behavior in marital relationships. Some scholars have found that premature ejaculation patients really have different performance in terms of nerve conduction and sex hormone levels than normal people, and they believe that premature ejaculation patients have a physiological response that is easily aroused and overly sensitive. Some scholars even believe that premature ejaculation represents an evolutionary behavioral pattern of the species. From an evolutionary point of view, males who are able to ejaculate within a shorter period of time have a higher chance of fertilizing females and reproducing offspring. In contrast, males that take longer to ejaculate and mate are more likely to be invaded or killed by other males or even other species during the mating process, so premature ejaculation may be the result of evolutionary selection. Treatment of premature ejaculation Treatment of premature ejaculation includes psychological and behavioral therapy, local therapy, oral medication and surgery. The goal of treatment is to improve the patient’s ability to control ejaculation by increasing the sensory domain values of the penis and adjusting behavioral reflexes. Psychological and behavioral treatment for premature ejaculation needs to be performed by a professional psychiatrist, and the effectiveness is closely related to the experience of the doctor. A commonly used method is sexual concentration training. Behavioral therapy includes increasing the frequency of ejaculation, adopting a female on male sexual position, stop and start ejaculation, squeeze technique, and pelvic floor muscle contraction exercises. Specifically, such as: when the male feels the ejaculation will be paused, the woman immediately lift the body from the male, or even press the glans below three to four seconds to reduce arousal, to rest for fifteen to thirty seconds before continuing. Other methods include diversions and changes in body position can also be used. In addition, the improvement of the relationship between husband and wife or sexual partners, emotional rapport, open communication, mutual understanding of the sexually sensitive areas of both parties, as much as possible more sexual foreplay and post-sex care, can improve sexual satisfaction and naturally solve the tension and shock caused by premature ejaculation on the sexual life of both parties. The purpose of local penile treatment is to reduce the sensitivity of the penis head and penile skin and increase its sensory domain value. Such as the use of condoms, circumcision deng. Local treatment is commonly used 2% lidocaine gel, applied to the head of the penis 10 minutes before intercourse to reduce the sensation of the penis and prolong the latency time of ejaculation. It can be washed away during sexual intercourse or with a condom. The shortcomings of topical treatment for premature ejaculation are numbness of the penile head and decreased pleasure. There are medications available specifically for the treatment of premature ejaculation. Adverse effects of commonly used drugs such as tricyclics are nausea, dizziness and erectile dysfunction. Dapoxetine is a newly developed drug by Janssen specifically for premature ejaculation, and its effect is similar to the above-mentioned drugs. Surgical methods for premature ejaculation are less commonly used and the results are not yet definitive. The main principle is to selectively cut the sensory nerves of the head of the penis and reduce the sensitivity of the head. In conclusion, patients must unload their psychological baggage and discuss their hidden illnesses with their physicians, who in turn must listen carefully to the patient and perform the necessary tests to understand the real cause of premature ejaculation, whether it is organic or psychological in nature, whether it is due to the patient’s own factors or to the social and cultural background, etc. If the cause of premature ejaculation is organic, the primary lesion should be actively treated and the problem can be solved. If it is functional, the factors that cause sexual tension should be excluded, and under the premise of giving correct sexual knowledge education and guidance, the patient should keep his spirit happy and relaxed, and both sides should cooperate and understand each other to achieve harmonious interaction between the two sides in sexual life and ordinary life, after which, the “fast shooter” will naturally disappear, and the sexual life of the The spoilers or shadows will naturally disappear.
