Irregular sex life for a short period of time usually does not have obvious health effects. If sex life is irregular for a long period of time, it may affect the mental health and physical health of both men and women. Regular and moderate sex life can help enhance the relationship between husband and wife, and allow both parties to obtain psychological and physical satisfaction, which is beneficial to health. If sex life is irregular for a period of time occasionally, it usually does not affect the physical and mental health of both partners. However, prolonged irregularity in sex life, including excessive sex or no sex for a long time, may bring about certain adverse physical and psychological effects on both men and women. Irregular sex life may affect mental health, such as anxiety, depression, irritability, low self-esteem and other negative emotions. On the physical side, irregular sex life may lead to prostate problems in men, such as excessive sex will lead to inflammation of the prostate gland due to repeated congestion, and may also lead to impotence and other problems. For women, irregular sex life may lead to frigidity, gynecological diseases and endocrine disorders. It is recommended that men and women maintain a moderate and regular sex life, pay attention to sexual hygiene, and take proper contraceptive measures when they do not plan to have children.
