In clinical practice, we often encounter the problem of premature ejaculation, what exactly is premature ejaculation? Some patients will ask the doctor, “Doctor, when I had sex for the first time, my penis ejaculated after just a few movements, what happened, is it premature ejaculation?” Is it premature ejaculation?” and “I ejaculate very quickly when I masturbate, and also very quickly when I have sex with my wife?” Other patients may ask, “I can have sex with my wife for five or six minutes or seven or eight minutes, but I ejaculate before my wife reaches orgasm, is that premature ejaculation?” Now let’s explain what exactly is premature ejaculation, I believe that through the following explanation, you can initially determine what is premature ejaculation. The International Society for Sexual Medicine has adopted a new definition of premature ejaculation, the first evidence-based medical definition. “Premature ejaculation is a male sexual dysfunction characterized by: always or almost always ejaculation before or within about 1 min after vaginal entry, inability to delay ejaculation after full or almost full vaginal entry. and negative personal outcomes such as distress, apprehension, frustration, and/or avoidance of sexual activity”. According to the above definition, premature ejaculation has the following characteristics: 1. Duration. Premature ejaculation is generally set for one month and is sustained for a month with rapid ejaculation. If rapid ejaculation occurs when having sex for the first time in a new marriage or after a long period of time without sex or once in a while, several times rapid ejaculation cannot be considered as premature ejaculation and must be sustained. In addition, there are two special kinds of premature ejaculation. It is lifelong premature ejaculation, which means that there has been premature ejaculation since the first sexual intercourse. There is also a kind of secondary premature ejaculation. That is, there was a normal sexual life before and the time was normal, but premature ejaculation was caused by some reason. 2. Stable sexual partner. Many young patients do not have a fixed sexual partner, and occasionally a few times short time that is identified as premature ejaculation, this is also not right. Even if you apply medication, you need to have a fixed sexual partner and a stable sex life so that you can detect the effect of treatment. 3, satisfaction. Sometimes, some patients ejaculate after the penis enters the vagina for 3-5 minutes during sex, while the woman has not yet reached orgasm, which can also be considered as premature ejaculation if it is always like this. Even if sometimes the duration of sex is relatively short, but both husband and wife reach orgasm sex, this is not considered premature ejaculation. A high quality sex life can make couples release stress, which is good for physical and mental health. 4, the sense of control. In simple terms, it is the ability of the male partner to control ejaculation, not wanting to ejaculate when that ejaculation, no control. If some patients just enter the vagina that ejaculation, can not control. Or just a few thrusts that ejaculate. 5. Psychological problems. In fact, the more serious effect of premature ejaculation is psychological problems. The adverse effects of premature ejaculation are often more than the sexual dysfunction itself, premature ejaculation can affect the self-confidence of male patients, but also cause discord in the relationship between sexual partners, and then fear of sex, leading to mental distress, anxiety, embarrassment and depression, which can affect sexual desire and interest in life. Therefore, premature ejaculation patients can often be seen in male clinics with heavy ideological pressure and reluctance to talk to doctors about their condition. For the treatment of premature ejaculation, a combination of Chinese and Western medicine is recommended, and no specific explanation will be given here.
