If the sex life is not harmonious and the sex climax fails to come, the congestion of breast will disappear very slow, and the swelling and pain of the breast and related discomfort can occur. In fact, this is caused by breast consensus and is one of the reasons for breast hyperplasia. The frequent congestion inevitably will bring internal chaos of breast.

If there is a long-term lack of sex life, the breasts, as sexual organs, will not be retained by sexual climax for a long time, and the structure and function of the breasts cannot be well "exercised". This also makes the physical hyperplasia and re-aging of the breasts not smooth, thus increasing the incoming of breast hyperplasia. In addition to the hyperplasia of mammary glands, the disharmony of sex life will cause swelling pain of breasts and inducing breast cancer. Statistics show that, among breast cancer patients, the proportions of elderly unmarried women with low sexual function and widowed women were significantly higher. This suggests that the risk of breast cancer increases significantly in women who have abnormal sex lives and are sexually inactive.

Sex life can help relieve the pressure in life and work, relieve the tension, and make people happier, more fulfilled and more confident. If the women are not satisfied with sex life, they will feel upset and impatient. Start a quarrel by using trivial matters as an excuse. Some suffer from neurological disorders.

The survey found that the impact of sex life is an important reason for some people's insomnia. When a person is in a period of high sexual desire but cannot get physiological release for a long time, the nervous system is at activated state, and insomnia comes then.This is a more prominent problem to women. This is because there is a big gap between men and women's sexual desire, sexual climax and degrading of sexual desire. Men's sexual desire can be quickly stimulated, and they can reach the climax quickly throughout sexual intercourse. After the climax, their sexual desire fade quickly. Therefore, as long as the men reach the climax (even after masturbation), they can fall asleep quickly.

However, women are different. Women's sexual desire must have a long process to initiate, and the "platform" period is long. Even after reaching the climax, the sexual desire will fade slowly. Hence, women are more difficult to achieve perfect harmony during the sexual intercourse compared to men, and women are easier to suffer from insomnia. Therefore, American psychologists pose that the lack of normal sex life or the disharmony of sex life is an important reason for women's insomnia.

If women are not satisfied with sex life, the sexual response is blocked, and the congestion of the pelvic and external genitals fails to disappear timely, the chronic pelvic hematocele will appear. If sexual desire is not satisfied for a long time, the women’s uterus with chronic pelvic hematocele will be larger by 2-3 times. Then the women are prone to a series of gynecological inflammation such as vaginitis, uterine inflammation and chronic pelvic inflammatory disease.  

Sex life can greatly relax the living and mental pressures that people receive in life. It can better balance the nerves, endocrine and immune system. In a family of sexual disharmony, the couples do not agree with each other, often quarrel and do not give-and-take, resulting in a nervous atmosphere. This will make people worried, anxious and depressed, and unwilling to eat and sleep and the fatigue will continue being unabated, reducing immune function and causing diseases. This is often the cause of gastric and duodenal ulcer, hypertension, coronary heart disease, and even one of the reasons for cancer.

The disharmony between husband and wife has the aforementioned dangers. So we must pay attention to it. At the same time, we can use some sex toys to make the sex life between husband and wife more harmonious.
