Woman goes to the doctor

Woman goes to the doctor for a checkup as she has been unsatisfied with her sex life and is told her vagina has become rather loose over the years. Upset she returns home and laying a mirror on the floor, gets naked, straddles the mirror and starts to examine herself. Her husband walks in and surprised to find his wife naked, asks what she is doing. She tells him what the doctor said. He replied "OK, but be careful you don't fall into that big hole".
