Vaginal/Urinary Tract Changes
With advancing age, the walls of the vagina become thinner, dryer, less elastic and more vulnerable to infection. These changes can make sexual intercourse uncomfortable or painful. Most women find it helpful to lubricate the vagina. Water-soluble lubricants are preferable, as they help reduce the chance of infection. Try to avoid petroleum jelly; many women are allergic, and it damages condoms. Be sure to see your gynecologist if problems persist.
Within four or five years after the final menstrual period, there is an increased chance of vaginal and urinary tract infections. If symptoms such as painful or overly frequent urination occur, consult your doctor. Infections are easily treated with antibiotics, but often tend to recur. Douching is not thought to be effective in preventing infection.
Alleviating vaginal dryness and urinary problems
Use a vaginal cream or lubricant (avoid petroleum jelly) to help reduce pain from dryness during sexual intercourse.
Urinate before and after sexual intercourse to help prevent bladder infections.
Drink plenty of fluids and empty your bladder frequently.
Try Kegel exercises (tighten and relax the muscles you use to stop urination) daily. They strengthen the vaginal muscles, enhance orgasm, and help prevent incontinence.
