The World Health Organization has defined three elements of sexual health: a capacity to enjoy and control sexual behavior in accordance with a social and personal ethic; freedom from fear, shame, guilt, false beliefs, and other psychological factors inhibiting sexual response and impairing sexual relationships; and freedom from organic disorders, disease, and deficiencies that interfere with sexual and reproductive functions. Medical studies of human sexual function and activity have provided no evidence that having attained a certain age is, of itself, reason to discontinue participating in and enjoying sexual intercourse.
