From the current practice of sexual life, there are roughly three statements:
Night usually refers to around 22:00, which is the time for a considerable number of people to sleep. People who hold this view believe that sexual activity requires a lot of physical energy. At this time, having sex immediately after that, both parties can rest and maintain sufficient energy the next day
It's better around 6 o'clock in the morning.
People who hold this view believe that after a night of rest, their physical strength is restored and they have good energy during sexual activity. In addition, from a physiological perspective, the concentration of adrenal hormones in the human body is the highest, and sexual desire is also strongest at this time. Having sex during this time can quickly enter a state of sexual excitement. After sexual intercourse, one cannot rest immediately and must work and study immediately, but the physical exertion of a one-time life is not significant. Having sex in the morning without feeling tired or uncomfortable after sex is a way to determine if it is suitable for oneself. (Note: Sexual activity should not occur in the early morning)
People who hold this view believe that modern people's pace of life is very fast. After 8 hours of study and work a day, they become tired and want to enjoy a relaxed night life at night. They also engage in necessary social interactions, usually staying up late at night. In this situation, engaging in sexual activity may result in insufficient physical strength and mental satisfaction for both parties. Take a nap, get the necessary rest time, recover physical strength and energy, and sleep for a few hours after sexual intercourse.
The above three statements each have their own perspectives and reasons. Which time has absolute advantages and disadvantages, but the habits of quite a few couples are the most common. In fact, the choice of sexual time is in the hands of all couples. When to have sex must be determined based on both parties' work, study arrangements, physical, mental, sexual habits, and preferences. For example, people with weak functions can help compensate for their weaknesses starting in the morning. People who work hard tend to maintain strong work ability before going to bed.
In short, there are no certain rules for the time of sexual activity. As long as couples acknowledge and enjoy it together, it will not affect each other's work and study the next day. Any time is appropriate and there is no need to insist on it uniformly.
