When couples have sex, the duration is usually about 5-15 minutes from the beginning of sexual excitement to the end of ejaculation. Of course, each couple's physical condition and sexual habits are different, even for the same couple, the specific circumstances and environmental conditions of each sexual activity are different. Therefore, it is difficult to determine a standard for how long each sexual activity should last.
Some people believe that the longer the duration of each sexual activity, the more sexual satisfaction they can obtain. This view is not scientific. Sexual physiology research shows that a long duration of sexual activity is detrimental to both parties' health.
First, during sexual life, not only the sexual organs of both men and women are in a highly congested state, but many tissues and organs of the human body are involved in this special physiological process from the sexual excitement stage to the orgasm stage. For example, the overall muscle tension is significantly increased, the heart rate is accelerated, myocardial contraction is strengthened, blood pressure is increased, respiration is deepened, blood vessels in the skin of the whole body are expanded, and sweating is increased.
As a result, the body's energy consumption significantly increases and metabolism increases. If the time spent having sex is prolonged, it can cause excessive energy consumption in the body and make people feel tired, and even cause both parties to experience mental fatigue, muscle soreness, general fatigue, and other discomfort, which is bound to affect the work and labor of the next day.
Secondly, during sexual life, the sexual organs of both men and women are in close contact and activity under a highly congested state. If the time is too long, it is easy to cause various diseases. Clinical evidence shows that the duration of sexual life is too long, women are more likely to cause urinary infections, menstrual disorders, and men are prone to cause prostatitis.
