We are a couple in the late 60’s. After reading other reviews, I thought I would try one. I was not sure my wife will go along with it. To my surprise she did. I kept the intensity low and well lubricated. Initially, she climaxed in a few minutes only with clitoral stimulation. Then, gently proceeded with vaginal stimulation. She came about 2 more times. It did not require any rapid movement but the vibration did what was needed. I just stabilized it and she moved herself to find the “spot”. I think the whole experience surprised my wife. What was surprising was how little time it took and and did not cause any discomfort. With the old way, even if you were gentle and used lubrication it was hard on the aging integument.
I would recommend this to any older folks to rekindle the joy of sex. I hesitated to post a review as this(we are old fashioned)but I know there will be others who can benefit from our experience.
