Women's sexual desires naturally fluctuate over the years. Highs and lows commonly coincide with the beginning or end of a relationship or with major life changes, such as pregnancy, menopause or illness. Some medications used for mood disorders also can cause low sex drive in women.
If your lack of interest in sex continues or returns and causes personal distress, you may have a condition called sexual interest/arousal disorder.
But you don't have to meet this medical definition to seek help. If you're bothered by a low sex drive or decreased sex drive, there are lifestyle changes and sexual techniques that may put you in the mood more often. Some medications may offer promise as well.
