I wish you success with that, Dread. I also am uncut, and have found constriction type hangers (The Bib, Malehanger, [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]LM[/words] etc) to be extremely challenging. I used to have a Bib hanger and eventually threw it out. I could hang weight, for sure, and fairly heavy weight, but not without being in almost constant and increasing pain. Problem? The foreskin keeps getting pinched, as I've mentioned in a lot of posts over the years. It doesn't' matter, at least not to me, how much I retract the foreskin. It still somehow pinches some, and it hurts like a SOB from hell! I have an [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]LM[/words] that I ordered a couple months back. I tried several different methods to avoid that pinching, but was unsuccessful. I just cannot sit there for 20 minute sets hanging, or even stretching, while grimacing from being in so much pain. It has been parked in my closet since 3 days after receiving it. I'll probably list it for sale here on [words=http://www.mattersofsize.com/join-now.html]MOS[/words] sometime soon. Nothing wrong with the device. Works like a charm...IF,IF,IF...you've been circumcised. Otherwise, it's a bitch to make work. For uncut guys like us, in my opinion, the vacuum hangers are the best option. They grip the glans and your foreskin is not an issue. Might not be able to hang as heavy a weight, but I'm not sure how important that is. Is hanging 25 pounds for 15 minutes more effective than 10 pounds for an hour? I don' t know. This is not an exact science. After all, people like the folks at PF and [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]SG[/words] etc all say you can gain with relatively very low stretch, but over long periods of time. Others say you have to use heavy weight and then an [words=http://www.phallosan.com/shop/catalog/default.php?z=eNortjIxtVKyL0pNszWxMFcrSSxKTy2JL0hMT7U1UisoykyxtbBQSy4tLsnPjS8uKcrMS7dVsgZcMMpbEbo%2C]ADS[/words] to keep the stretch. Others say the [words=http://www.phallosan.com/shop/catalog/default.php?z=eNortjIxtVKyL0pNszWxMFcrSSxKTy2JL0hMT7U1UisoykyxtbBQSy4tLsnPjS8uKcrMS7dVsgZcMMpbEbo%2C]ADS[/words] is not necessary, and the heavy weight is sufficient. Maybe one day there will be a consensus, but for the time being, it's a bit of a crap shoot. But I share your frustration with using these devices while being uncut. Been a problem for me for years and years.
