Lying next to their lover at night, many people will feel no "sexual interest" and may even suffer from frigidity. Some people attribute this to aging, some think that their partner has lost their attractiveness, but few people think that this may be caused by some of the following bad habits.

Stay up late at night. Laumann, a professor of sociology at the University of Chicago, believes that staying up late causes many young people to become "premature". For men, sleeping too late can affect penile erectile function and destroy sexual desire. For women, it will cause deterioration of skin and figure, and reduce sexual confidence.

Watching porn all the time. A study in Taiwan found that the more men watch pornographic films, the more they worry about their sexual skills. At the same time, porn can also make men become insensitive to stimulation, have difficulty in erection, become obsessed with masturbation, and ignore their loved ones.

I was too full for dinner. Many modern people have a very rich dinner, and they will overeat without realizing it. French sexologists found that eating a big meal before sex will reduce the quality of sex. Because eating too much will make people drowsy, and a large amount of blood will enter the gastrointestinal tract to help digest food, and the blood supply to other parts of the body will be reduced accordingly, which will affect male erections and female sexual feelings.

Complaining is always on your lips. A survey conducted by the Kinsey Institute of Sexuality in the United States shows that couples who often complain about each other will have less and less sex, and couples who bring household chores to bed are more likely to deteriorate. Topics such as family financial status, children's education, and household chores all affect sexual desire.

The computer goes into the bedroom. Multiple studies have shown that the "invasion" of electronic products such as computers and mobile phones into the bedroom will seriously affect sex. A survey by Dr. Anita H. Clayton, a professor of gender studies at the University of Virginia in the United States, found that playing on the computer before going to bed will reduce the chance of having sex by 30% and may also cause emotional problems.

Drink too much milk. Milk has a calming and hypnotic effect. Drinking too much milk before sex will only make people fall asleep.

Sedentary and inactive. A survey on "Exercise and Sexual Desire" conducted by American sexologists on 2,000 people showed that people who do not exercise are 38% more likely to suffer from sexual frigidity. Active exercise can help keep you in shape and enhance your sexual desire.

I have long-term constipation. People suffering from chronic constipation are often accompanied by low sexual desire or abnormal sexual life. The pelvic floor of these people contracts spasmodically, resulting in low sexual sensation and indirectly reducing sexual desire.
