Hi cheers2u, you are doing the right thing by using the 2 small rings together. Just let me know the diameter of the inner ring in mm's just so that i can check you have got the small rings. Im guessimg that it may have been a while since you had a firm erection. I would recommend using the pump on its own daily as an exerciser to recondition the penis and work on improving the blood supply. Do this for a while and then try again with the rings. There are things that will affect the erection and i would try avoiding ; eating a heavy meal , drinking alcohol etc just before. You can use viagra etc with the pump if necessary but once you have recondtioned the penis a bit you should be well away. Please feel free to email me off forum if you prefer for further help as it would be useful to know a bit more about your history e.g. diabetic, blood pressure, prostate problems etc and i may be able to help further,
best wishes
Steve
