How often should couples have sex? If we really had to give a timeframe, I honestly couldn't say. Even if there are studies on what constitutes a normal frequency, it's only a reference. Ultimately, it depends on the communication between the couple and their individual needs.

Normal sexual intercourse lasts 5 to 15 minutes each time, but this varies depending on each couple's physical condition, sexual needs, and habits. Moreover, the environment and conditions for each sexual encounter are different, so the duration will naturally vary each time. It is difficult to give a definite answer as to how long is appropriate.
How often should couples have sex? Generally speaking, once a week is appropriate. However, this largely depends on factors such as physical strength and energy. It is impossible to regulate it according to existing rules. If two people are sexually aroused, they can have sex at any time. Once a day or several times a day is also possible. Just like time, there is no fixed limit to the number of times.
So what factors influence sexual performance?
1. The influence of emotions

If both people are in a good mood and have a lot of interest, it's more suitable to stimulate their interest in sex. However, if one person is in a bad mood or not in a good mood, it will affect the quality of sex life and may even lead to sexual apathy, which can seriously damage their health.
2. Nutritional effects
Adequate nutrition and a healthy body lead to better sperm quality and higher quality in men. Eating plenty of protein-rich foods can help maintain sexual function.
3. Smoking and drinking
Heavy smoking and drinking can cause erectile dysfunction and premature ejaculation, as well as a decrease in libido. The effects of tobacco and alcohol on sexual function are reversible, and most people's sexual function can gradually return to normal after quitting smoking and drinking.
4. Housing conditions
If the room is dirty and messy, it will naturally put you in a bad mood, let alone engage in sexual activity. Normal life will be affected, and even if you share a bed, you will not be interested in doing anything else, which will lead to decreased libido.
