Bahahahahaha!! Im sorry but 20 months??? BS. I'm sure most men having one last more then a day or 2 would think, hey somethings up..... maybe I should go get this thing looked at. Maybe I should stop riding my bike.. These seem like reasonable thoughts.
Now if it is by some miricale true, then enjoy it. Don't be a softy and be sensitive. Be a real man, hard and tough.
