When couples have sex, the normal duration is approximately 5-15 minutes. Of course, the physical condition and sexual habits of each couple are not the same. Even for the same couple, the specific circumstances and environmental conditions of each sexual activity are also different. Therefore, it is difficult to establish a standard for the duration of each sexual activity.
Some people believe that the longer the duration of each sexual activity, the more sexual satisfaction one can obtain. This view is not scientific. Studies on sexual physiology have shown that prolonged sexual activity is detrimental to both parties' health.
Firstly, during sexual activity, not only are the male and female sexual organs in a highly congested state. And from the Sexual arousal period to the climax period, many tissues and organs of the human body are involved in this special physiological process, for example, the muscle tension of the whole body is significantly increased, the heart rate is accelerated, the myocardial contraction is strengthened, the blood pressure is increased, the respiration is deepened, the skin blood vessels of the whole body are expanded, and the perspiration is increased, so the energy consumption of the body is significantly increased, and the metabolism is enhanced. If I have sex for a long time, it will cause the body's energy to consume me and make me feel tired. Even causing both parties to experience mental fatigue, muscle soreness, and overall fatigue, which will inevitably affect their work and labor the next day.
Secondly, during sexual activity, both male and female sexual organs are in close contact and activity in a highly congested state. If the time is too long, it is easy to cause various diseases. Clinical evidence shows that prolonged sexual activity is more likely to cause urinary tract infections, menstrual disorders, etc. in women. Men are prone to Prostatitis, etc.
