According to Doctor Pham Quang Khai, there is currently no evidence that frequent sexual activity directly reduces lifespan. However, it can lead to weakness, fatigue, and general poor health. Medical intervention is only necessary if an individual exhibits abnormal behaviors such as sex addiction, lying to conceal these actions, or experiencing obsession, restlessness, and discomfort when unable to engage in excessive sexual activities, leading to decreased work productivity and loss of control.
The American Urological Association (AUA) states that the normal testosterone level for adult men is 300 nanograms per dL. Below this level, a patient is diagnosed with low testosterone, which affects sexual desire and ability. After age 30, testosterone levels decrease by 0.8-1.4% annually. Healthy sexual activity can reduce stress, improve sleep, and help prevent chronic diseases associated with aging.
Men's sexual desire varies with age. For those aged 18-29, the average frequency is 112 times per year, or two times per week. This demand decreases to 86 times per year (1.6 times per week) for those aged 30-39. For individuals aged 40-49, the frequency is approximately half that of those in their 20s, at 69 times per year. However, sexual frequency also depends on various factors, including gender, age, lifestyle habits, living environment, occupation, and a partner's needs.
Sex addiction increases the risk of inappropriate and criminal behavior. Prolonged excessive sexual desire can also have psychological impacts, affecting marital, partnership, and social relationships. Older individuals, in particular, should avoid overindulgence, as it can negatively affect their health due to existing underlying medical conditions.

Doctors advise maintaining an average sexual frequency of one to two times per week to prevent discomfort and stress from accumulated desire. It is important to avoid stimulants and addictive substances that increase sexual desire. In cases where excessive desire is caused by medical conditions, doctors need to identify the root cause and provide treatment through psychological counseling or medication.
If you notice unusual symptoms due to frequent sexual activity, consult a urologist or andrologist.
