Sexual disorder is any condition which interferes with an individualís ability to engage in sexual activity or impairs oneís sexuality. It is known that the sexual function decreases with age due to differences in hormone levels. There are several known sexual disorders which affect primarily aged populations. Sexual aversion disorder is an avoidance or fear of sexual contact; female sexual arousal disorder is failure of lubrication/swelling response; male erectile disorder is failure to gain an erection or maintain it if it occurs; orgasmic disorder is the inability to reach a climax stage in both men and women; vaginismus is an involuntary spasm of the vaginal muscles which makes sexual intercourse impossible. It is important to know that these disorders can have physiological as well as psychological roots. For example, there are many conditions and drugs which may cause decreased libido and sexual aversion disorder. Treating sexual disorders depends on the type and causes of the disorder, but there are many known aphrodisiacs, natural and synthetic.
