Sexual dysfunctions are disorders related to a particular phase of the sexual response cycle. For example, sexual dysfunctions include sexual desire disorders, sexual arousal disorders, orgasm disorders, and sexual pain disorders. If a person has difficulty with some phase of the sexual response cycle or a person experiences pain with sexual intercourse, he/she may have a sexual dysfunction.This disorder may be present when a person has decreased sexual fantasies and a decreased or absent desire for sexual activity. In order to be considered a sexual disorder the decreased desire must cause a problem for the individual. In this situation the person usually does not initiate sexual activity and may be slow to respond to his/her partner's sexual advances. This disorder can be present in adolescents and can persist throughout a person's life. Many times, however, the lowered sexual desire occurs during adulthood, often times following a period of stress. Female sexual arousal disorder is described as the inability of a woman to complete sexual activity with adequate lubrication. Swelling of the external genitalia and vaginal lubrication are generally absent. These symptoms must cause problems in the interpersonal relationship to be considered a disorder. It is not unusual for the woman with female sexual arousal disorder to have almost no sense of sexual arousal. Often, these women experience pain with intercourse and avoid sexual contact with their partner.
