The International Society for Sexual Medicine (ISSM) defined the criterion for primary premature ejaculation as 1 minute in its 2014 guidelines, meaning that more than 1 minute is usually normal. The ejaculatory latency period of men in China is 3-10 minutes, so generally as long as the time between entering each other and starting sexual intercourse to ejaculation is more than 6 minutes, it is already considered above average. So, if once in a while not so lasting, even a few minutes can not do, do not worry too much, the duration of sex will be affected by the physical condition at the time, psychological state and other factors, the occasional stay up late, drunk, or even too excited, can lead to not lasting, it does not explain what the problem. Avoid bad lifestyle, adjust your body and mind, you will have a chance to get up again from the fall there. How long is a good duration? It mainly depends on the body’s tolerance. Sex is a need to mobilize most of the tissues and organs of the body “big project”, the brain, heart, muscles are involved, once the duration exceeds the range they can bear, but also may affect the next day’s normal work, life, its exhaustion is no less than the day before running a marathon. Therefore, there is no need to blindly climb, the duration is too long can also hurt the body. Only if the body can hold on to the end can it really guarantee a higher quality and individual experience. Of course, if the ejaculation latency is less than 1 minute for a long time, you should consider if there is erectile dysfunction. There are many factors that can lead to erectile dysfunction, including emotional disharmony or concomitant illnesses such as high blood pressure, diabetes, depression, and anxiety. But erectile dysfunction is not incurable, if necessary, you need to actively seek medical attention, usually more active communication with partners, to understand each other’s needs and learn about sexual life, and can help prolong sex with the help of professional doctors through the application of relevant medication. The correct way to open adult life is to find the problem and solve it in time, and the same goes for sex. If the “not lasting” is not something to be ashamed of, it must be treated correctly and actively seek medical attention. The last thing I would like to remind you is that sex time is not the more durable the better, or depends on the body’s tolerance; the quality of sex life does not depend entirely on the length of time, as long as both sides can be satisfied, it belongs to a healthy, good sex life.
