I've been using a pump on an off for a few months, and I've noticed that I get some roll over now that I didn't used to. I'm cut, but the skin is loose and I can pull it back over when soft. Now it rolls over when I sit sometimes. I don't use the pump too much because I don't like the freaky puffiness it can give, but it's good for some solo fun once in a while. I don't expect I will ever get a full restoration anyway, and it isn't really that important to me since I don't miss what I never knew I had.
