How often a 48 year old woman will have sexual needs depends on individual circumstances and cannot be generalized. Under normal circumstances, women’s ovarian function gradually declines after the age of 48, the secretion of estrogen in the body gradually decreases, and the sexual desire will also slowly decrease, usually 1-2 times a month. At this time, because of the decrease of estrogen in the body, the secretion of glycogen by the vaginal epithelium decreases, and the secretion during sexual intercourse decreases accordingly. Since some women may experience painful intercourse or bleeding during intercourse, it is necessary to increase caressing time before intercourse or use adult lubricants to improve vaginal dryness if there are no contraindications. In addition, older women who have sex need to pay attention to sexual hygiene in order to avoid local infections that can lead to gynecological diseases.
