One of the familiar challenges for menopausal women during sex is a lack of lubrication. Really the lack of lubrication is just one of the symptoms of reduced estrogen due to the natural aging process. Estrogen helps keep our tissue young and supple. Without it, things can quickly fall apart. Intercourse can become painful due to lack of lubrication. Thin tissue and bladder infections can become problematic. Decreased Estrogen causes all kinds of issues.
