Although men go through some sexual changes as they age, they do not lose their desire or their ability for sexual expression. Many individuals remain sexually active throughout their older years.
As men get older, they are more likely to suffer from medical problems, and there are a number of conditions (e.g. heart disease and diabetes) that can cause erectile dysfunction, and can diminish the capacity for and interest in sex. Also, the side effects of several medications used to treat some of these conditions can compound the problem.
