Most sexologists agree that a healthy and satisfying sexual life is very important to romantic relationships. Moreover, it promotes physical and mental health in both partners. However, couples can vary considerably with regard to the importance of sexuality in their lives. Some couples can maintain a close and satisfying relationship with little sexual activity. For many other couples, sexual intimacy is an important part of the relationship and disruptions to sexual life can either cause relationship problems or be a symptom of them. It is also important to note that sexual activity generally decreases with age, particularly in the last few decades of life. Because of this, older couples may place far less emphasis on sexual intimacy than do younger couples. Nonetheless, there are many older couples for whom sexual satisfaction is still important. As the elderly population increases and more people stay physically and mentally vigorous late into their life, it is likely that the topic of geriatric sexuality will gain more attention.
