Hormonal changes are another important part of aging. For women, declining estrogen around menopause can contribute to vaginal dryness, discomfort during sex, and changes in desire. Men may experience a gradual decline in testosterone, although the degree varies widely. Having less intimacy does not cause these normal hormonal changes. Instead, hormonal changes and physical discomfort can sometimes make intimacy less appealing unless the underlying issue is addressed.

Sleep and physical comfort may also change, although not always for the reasons people assume. Feeling safe and emotionally connected can help some people relax before bedtime, while loneliness and anxiety can interfere with sleep. Likewise, affectionate touch may temporarily reduce tension, but a lack of touch does not automatically cause stiffness or loss of flexibility. Age-related discomfort is more commonly connected to arthritis, injuries, reduced mobility, and other health conditions. Yet there is one important fact that can change how people think about intimacy altogether.
