If your love life has stalled, one of the questions you need to ask yourself is whether or not you get aroused when you think about sex. Your answer is crucial, because arousal and sex drive (libido) are two different things.
If you desire sex and are in the mood for it but your vaginal zone will not respond by lubricating and preparing for intercourse, then what you’re suffering from is an arousal disorder, defined as the inability to achieve or maintain a state of arousal. An arousal disorder can occur at the brain level and/or the genital level. But don’t automatically blame menopause. The lack of arousal may be due to:
Certain high blood pressure medications
Heart disease and diabetes
Antidepressant therapies, particularly SSRIs
Past pelvic surgery (including hysterectomy, traumatic childbirth, or a bladder lift), which can damage nerves in the vaginal zone
If you and your doctor rule out these possibilities, it’s time to look at your hormonal status. Estrogen is responsible for physically preparing your body for intercourse. But during menopause, estrogen levels are low, a condition that especially affects “female” areas that need estrogen to function.
