I agree with cherie, i had the same problem, go speak to GP and he will prescribe hormone treatment to help there is also a pill you can insert inside called vagifem which help to plump up the skin inside again, to get things back to normal.
talk to your doctor about estrogen testing...Im assuming you still have ovaries,,,they often dont function "right' when uterus is removed..if your low on estrogen and I bet you are the cure is simple...I choose the patch its easy and no bad side effects...its a simple blood test to determine if you need hormones.
