The endocrine and cardiovascular functions of men over the age of 60 are sufficient to maintain normal sexual behavior, if they do not suffer from any disease. The changes that occur in sexual life with increasing age are mainly the time needed for sexual arousal and the time needed to reach orgasm as well as the prolonged duration of the after-orgasm period, as well as the weakening of ejaculation, sometimes with little or no ejaculation. However, older people should not mistake this as a sign of physical decline, but should see the positive effects of these changes. These changes avoid the intense actions of sexual intercourse that are no longer meaningful to older couples. However, these changes lead to longer periods of caressing and intercourse between older couples. In this longer sexual activity, men and women pay more attention to each other’s feelings and get sexual pleasure from each other, thus benefiting physical and mental health. Although old age and chronic diseases can affect the sex life of the elderly, but most of the older men’s sexual function still exists. Those “elderly people have no sexual requirements”, “elderly people lose sexual function”, “elderly people should not have sex”, etc., are nonsense. Older people have the right and the ability to enjoy the pleasures of sex. In his book “Prevention and Control of Brain Aging”, Dr. Masatoku Asa Nagashi of the University of Tokyo, Japan, points out that people who do not have a sex life will suffer from sexual atrophy. A proper sex life helps keep the brain young, prevent brain aging and promote metabolism. Surveys around the world have shown that healthy and long-lived people in addition to good habits in life, another common feature is a loving husband and wife, have a normal sex life. Some information shows that the couple’s sexual life is not harmonious, the average life expectancy of men is 12 years shorter, women short 6 years. Single men have 15-20 years shorter life expectancy than married men. A survey conducted by Swedish researchers on 800 elderly people showed that discontinuing sex can lead to memory and intellectual decline, while elderly people with active sex lives have more energy and memory than those who live alone. Therefore, when we focus on the quality of life of elderly men, we cannot ignore the maintenance, restoration and improvement of their sexual function. The scientific studies mentioned above show that elderly people should have an active sex life, and an active sex life can enhance the health and longevity of elderly people. Even if for some reason the penis cannot get an erection or is not firm, you can use some drugs or devices that can help with erection to have sex under the guidance of a doctor, such as Viagra, which is a safe and effective drug.
