Suggest Treatment For Tightening Of Vagina

I AM HAVING PROBLEMS WITH MY VAGINIA GETTING SMALLER AS OF LATE. THE FREQUENCY THAT MY HUSBAND AND I HAVE HAD INTERCOURSE HAS SLOWED DUE TO LIFE CIRCUSTANCES. IS THIS THE PROBLEM. I AM 61 YRS OLD AND ENJOY SEX VERY MUCH BUT THIS IS CAUSING PAIN. I AM CURRENTLY USING A COMPOUND PRESCRIPTION PRESCRIBED BY MY UROLOGIST. I HAVE BEEN USING IT FOR 2 YRS NOW. I DO NOT HAVE VAGINAL DRYNESS JUST THE TIGHTENING OF VIGINIA.
