Have you had any progress with the lenghtmaster? Alot of people have issues when applying it and I honestly think that it's not the wrap but more of a positioning error. The wrap it's self is fairly straightforward as long as all skin is pulled back when applying and making sure there are no creases to cause pinching .
The position of which you attach the lenghtmaster is very important to avoid slipping and pain to the head of the penis. In my opinion, the same principles should be applied to attaching the lenghtmaster as they would to attaching a compression hanger.
Because of the amount of force you can generate with the lenghtmaster you must place it about half an inch behind the penis head , maybe more for some , and clamp down so the chamber grips to the internals of the penis. When this is done and force is applied the edge of the lenghtmaster will not touch the head of the penis allowing you to take advantage of the amazing force that can be applied.
Give it a try as I'm confident it will help out 👍👍
