Human sexuality is an extremely complex physiological and psychological process, and the duration of sexual intercourse varies greatly from couple to couple, and only a very small number of people can maintain more than half an hour in sexual intercourse. The key is the sexual feelings of both sides, as long as both sides can get sexually excited satisfaction and pleasure, that is, the perfect sex life. No sexologist has ever specified how long sexual intercourse should last. According to the survey, the average time of intercourse for men is 2 to 3 minutes. But you can’t think that less than this time is premature ejaculation. Because each couple’s sexual habits are different, their intercourse time at different ages is also different. Newlywed couples and couples who are reunited for the first time will ejaculate too early, which is considered a normal physiological phenomenon and cannot be considered premature ejaculation. In terms of time, it is normal for the penis to ejaculate after 2 minutes of vaginal penetration and pumping. Therefore, some sexologists have given two criteria for the normal duration of sexual intercourse: one is that it is normal to last more than 2 minutes or to pump more than 16 times from a medical point of view. The other criterion is to compare oneself with oneself, for example, if he used to be able to last half an hour and then suddenly dropped to 5 minutes, that is not normal.
