What is female sexual arousal disorder?

When a woman becomes aroused through thoughts and fantasies, physical stimulation, or both, blood flows to her pelvic region, causing her genital tissues to swell and her vagina to moisten. These changes indicate her physical readiness for sexual intercourse. With female sexual arousal disorder, however, the sequence breaks down, and the woman's body doesn't produce this necessary response. Sometimes this physiological response occurs, but a woman doesn’t feel realize she’s aroused. Female sexual arousal disorder is present when physiological arousal does not occur or is not perceived by the woman and this causes personal distress.
