Dryness of the vaginal mucosa is the result of hormonal changes in a woman's body, more precisely, a decrease in estrogen levels. Because of the pain associated with this phenomenon, some women refuse to have sexual intercourse. Water-based lubricants are a good solution. Attention! Avoid using oily lubricants such as tallow or petroleum jelly. Studies have shown that fatty lubricants are not as effective and cause irritation if used for a long time.
