Hi, I am a new member
and received my system about a week ago and I am very happy with its quality. However, I do have a painful problem with its use. I have tried using the system each day but I have found that the open end of the cylinder causes pain by pushing each time the pump is operated into my groin area. I have tried it with and without the rubber cylinder ring but there seems to be no difference. The vacuum is fine and as stated each time the pump is operated the cylinder pushes deeper into my groin. My groin area is quite fleshy and this may be causing the problem. ANY IDEAS PLEASE
