Older women often lose interest in sex because of physical issues. When Hormone Replacement Therapy (HRT) was demonized by one poorly designed study that has not been replicated, women refused it. As a result testosterone and progesterone drop to nearly nothing after menopause and create a condition called vaginal atrophy. Vaginal intercourse will then feel like being sliced with razor blades from the inside. HRT increases natural vaginal lubrication and desire. While shame and trauma play a part in all age groups of women not wanting sex, actual physical pain is the cause for many older women.
