During sexual intercourse, from the onset of sexual arousal to ejaculation, the normal duration is about 5-15 minutes. Of course, every couple's physical condition and sexual habits are different. Even for the same couple, the specific circumstances and environmental conditions of each sexual encounter are different. Therefore, it is difficult to set a standard for how long each sexual encounter should last.
Some people believe that the longer the duration of each sexual encounter, the greater the sexual satisfaction. This view is not scientific. Sexual physiology research shows that prolonged sexual intercourse is detrimental to the health of both partners.
First, during sexual intercourse, not only are the sexual organs of both men and women in a state of high congestion, but from the sexual arousal period to the orgasm period, many tissues and organs of the body participate in this special physiological process. For example, the tension of the whole body muscles is significantly increased, the heart rate is accelerated, the myocardial contraction is strengthened, the blood pressure is raised, the breathing is deepened and accelerated, the blood vessels of the whole body skin dilate, and sweating is increased, etc. As a result, the body's energy consumption is significantly increased and metabolism is enhanced. If sexual intercourse lasts for a long time, the body's energy consumption will be excessive, making people feel tired, and even causing both parties to experience mental fatigue, muscle soreness, and general weakness. This will inevitably affect their work and labor the next day.
Secondly, during sexual intercourse, the sexual organs of both men and women are in close contact and activity under a state of high congestion. If this lasts too long, it can easily lead to various diseases. Clinical evidence shows that prolonged sexual intercourse can easily cause urinary tract infections and menstrual disorders in women, and prostatitis in men.
