Lower estrogen levels decrease the blood supply to the vagina and the nerves and glands surrounding it. This makes delicate tissues thinner, drier, and less able to produce secretions to comfortably lubricate before and during intercourse. So, some women show a lack of interest in sex. Estrogen creams and oral estrogen can restore secretions and tissue elasticity. Water-soluble lubricants can also help.
Some women actually feel liberated after menopause and report an increased interest in sex.
They feel relieved that the children are out of the house and pregnancy is no longer a worry.
