I bought the pump in hopes of enlarging my clit size. I have a very small clit, that doesn't even come out of the hood. When I am arroused, you cannot even see my clit. I used it for the first time today and let me tell you, I love it! My clit swole and for the first time, I say my clit come of the hood. I just hope that with some routine pumping, my clit will enlarge in size.
