I just had my first session with the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]lengthmaster[/words] and wrapping was not an issue. Nailed it the first time. I use my own technique because Ive been using something similar to stretch with my hands. When you stretch with too much force, one of the main issues before hand fatigue is the grip slipping off the penis. I found out a while ago that just grabbing one square of toilet paper, fold it in half, and wrap it around the penis just under your "ok" [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]sign[/words] with your fingers is gonna be, and the grip stays there. The paper keeps sucking that humidity and doesn't move.
I applied the same principle to wrap for the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]lengthmaster[/words]. This time I grabbed 4 squares of toilet paper, fold the whole thing in half horizontally, not vertically, and wrapped it around my cock. Wrap it as tight as possible behind the glans, foreskin completely retracted. Of course be careful to not tear the toilet paper apart since is delicate. It wont be a tight wrap but just enough to put a good grip.
On top of it a wrapped the yellow rubber, this one as tight as possible. Then went into the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]lengthmaster[/words]. Tighten fast, and it stays there.
Awesome device!
