Men's sexual satisfaction depends on health, not Viagra

This is an interesting conclusion from a recent study at the University of Chicago: "Sexual activity, good quality sexual life, and interest in sex were higher for men than for women and this gender gap widened with age. Sexual activity, quality of sexual life, and interest in sex were positively associated with health in middle age and later life. Sexually active life expectancy was longer for men, but men lost more years of sexually active life as a result of poor health than women."
