I have been pumping for for 4 months. Like you, at first I saw very little change in the tube. After following the routine outlined by Avocet8 in the thread “Pumping 101”, I settled on a routine of 3-4 ten minute sets with jelqing in between. There is a little more expansion each set. Girth is the most dramatic, 1-1.5” extra by the end of the fourth set. FOLLOW AVOCET’S ADVICE. Your dick needs to get used to being pumped. Early on, I’d feel sore for hours from a 10-15 min set done exactly as advised, but now I only feel sore if I stop listening to the vets and really overdo it. Before you’ve conditioned your unit it is really easy to hurt yourself.
