Actually, Dr. C will prescribe a few days worth of Flomax (an alpha-blocker) for this reason. It does help the penis to hang longer and thus, allows the penis to heal in a more extended state. This does not mean that when you stop taking them your penis will stay that length. But it helps fight any bunching of the product that may occur due to
Turtling/retraction. Any filler is going to help with
Flaccid length, probably not to your full
Erection length, but it does make it longer. I do not think that you would have a problem.
