It’s normal to not have any interest in having sex from time to time. But if you don’t ever want to do it with your partner, it may be a sign of a medical condition. It can be due to high blood pressure, diabetes, arthritis or a neurological disorder. Of course, there are other factors too like hormonal imbalance, medications and so on.
Low libido is more common than you think. About one in five men lose their sex drive at some point in their lives. And the figure is presumably higher in women. Good thing, there are herbal remedies that can be used to relieve this problem.
