Feelings of sexual desire change for both men and women as they age. Sometimes the desire is more robust for only one partner, or the desire fluctuates so much for both partners that they are rarely in sync.

Over time, both men and women go through physical changes that affect sexual desire. Men may notice less sexual desire and erectile dysfunction, while women who have gone through menopause can also experience low libido as well as vaginal dryness, making intercourse painful.
