Premature ejaculation is generally defined as ejaculation that occurs no more than one minute after the man’s penis enters the woman’s vagina, or ejaculation that has already occurred before the start of sexual intercourse, but the specifics of the situation vary from person to person. Currently, internationally, there are three main elements in the definition of premature ejaculation: ejaculation latency in the vagina does not exceed 1 minute, the man can not control his own ejaculation, and sexual intercourse due to the dissatisfaction of sexual life caused by the disturbance. Only when these three elements are met can it be called premature ejaculation, so ejaculation time is not the only indicator of premature ejaculation. When there is premature ejaculation, couples therefore can not meet and produce great distress, it is recommended to go to the hospital for formal treatment. Normally, you should also live a regular life and exercise more to enhance your physical fitness.
