I agree that jelqing is good to do. However, I think jelqing is boring and I don’t like getting lubricant all over my hands. I find pumping to be a bit more enjoyable and pleasurable.
In the past couple years, I had not done much dedicated PE. The only thing I really did was force the bend in the opposite direction while masturbating. This is essentially the same principle as jelqing, where you are forcing blood into the weaker side. I was not making any progress, although admittedly I was not trying too hard. I though of the idea of using a rigid structure to help enforce the opposite bend, which would be more consistent and less tiring than using my muscles to force the bend. I started with a curved PVC connector used for plumbing, but it was not all that comfortable and it was hard to clean up. I then remembered that I had old Kaplan cylinders that I had not used in a few years. I wasn’t using them, so I didn’t care if I accidentally melted them with the torch. Plus, the Kaplan cylinders only cost around $50. When I torched the tube, it did not melt, catch fire, or burn. Rather, the tube got soft and melty. It was not too hard to bend the tube, although you need to watch out that you don’t introduce any hole in the tube wall that would break the vacuum. So, I am giving this a shot. Pumping/masturbating in a curved tube feels good. I would say that it feels better than trying to force the bend in the opposite direction with my hands while masturbating.
This is just an experiment. As far as I can tell, there aren’t any people on this forum who have said that they completely corrected their bend and now have zero curve. Plenty of people say that jelqing and pumping helps reduce the bend though. I went from 30 degrees to 20 degrees, but that was many years ago. Before trying this technique I searched for a couple hours for people selling curved cylinders and people reporting experimenting with this method. There are places that sell curved acrylic pipes, but that is quite a bit different that a comfortable penis cylinder. I also did not find anybody reporting that they have actually tried this bent cylinder pumping method. I don’t mind being the Guinea pig. I am not expecting any quick miracles, but I think the method has potential.
