Word of caution
I always advise guys to use some glans protection. Whether it’s the tender tape, micro-foam tape, glans cap or anything else. Even if you’ve developed a great amount of conditioning on your glans skin, you are still susceptible to a blister if your penis skin gets sucked into the vacuum port hole. If you don’t want to wrap, then I suggest a piece of gauze or a thin section of sponge at the bottom of your chamber to keep glans skin from being sucked into the vacuum port hole.
I’ve noticed some posts about weight hanging pump chambers. While designing the LG Hanger we experimented with a variety of chamber depths, and found that increasing the depth beyond the 2 1/4” - 2 1/2” mark provided no benefit. In fact any deeper actually became detrimental to getting a full shaft stretch. Ideally you want the connection / attachment to come from directly behind the glans on the shaft. If the chamber is the full length of your penis it really becomes nothing more than a penis pump and attaching weight to the end only increases the vacuum pressure inside the chamber, and you won’t get a full shaft stretch.
You can verify this for yourself with a little test….. take any penis pump chamber, install it and draw out vacuum. Let’s say you draw out 10 hg’s of vacuum pressure and the needle is static on the hand pump gauge. Now grab hold of the end of your penis pump chamber with one hand and pull on it and watch the Hg’s on the gauge spike. The harder you pull the higher the vacuum pressure climbs. Which really simulates what would happen if you attach weight to the end of your chamber. Ultimately you are not getting a full shaft pull and you’re only promoting the possibility of creating a blister with excessive vacuum pressure.
