While an active sex life can have numerous benefits for physical and mental health, there is limited scientific evidence to suggest that it can delay physical aging. There are a few other factors that can influence the aging process, including genetics, lifestyle, diet, and environment. While an active sex life may be one big plus that contributes to overall health and well-being, it’s not the only one.

It’s not surprising that people's sex lives to change as they age. Some people may experience decreased sexual desire, while others may continue to have an active and fulfilling sex life well into their later years.

For some, changes in hormone levels and physical health can contribute to changes in sexual function and desire. In women, menopause can result in vaginal dryness and decreased libido. In men, age-related declines in testosterone levels can lead to erectile dysfunction and decreased sexual desire.

On the other side, however, aging can influence a person's sex life as they age, including their overall health, stress levels, relationship dynamics, and personal preferences. Some people may find that their sex life improves as they age, as they become more comfortable with their bodies and sexuality, and have more experience in navigating relationships and communication.

Communication becomes more necessary with age: from talking with one’s partner to the healthcare providers about things such as any changes in their sexual function or desire. Additionally, exploring different forms of intimacy and sexual expression, like touch, kissing, and cuddling, helps maintain a strong emotional and physical connection with a partner, even if sexual activity is less frequent or intense than in earlier years.

Some studies have suggested that sexual activity may be associated with the following benefits:
