Hi guys,

Recently started vacuum extending. I love it, but having issues with getting a good vacuum. Yesterday i tried a cable binder/clamp to place around my sleeve below. I figured that air was coming in through the sleeve.

It works, but i get the cable binder tighter and tighter to create a good seal/vacuum.

When i didn’t use this i could sometimes get a vacuum, but i get a cold cockhead after like 5-10min. Same with using the cable binder.

I am wondering how dangerous vacuum extending is with regards to bloodflow. Is there still enough bloodflow to your cockhead? I’m kind of scared that i will do permanent damage if i keep on extending daily for 1 hour.

Thank you!
