i got the sizegenetics extender a long time ago, used for a while didnt really notice anything out of it, but not so sure i used it correctly.

i just remember the head of my penis being cold while it was on and i think it lost circulation, also the comfort strap got caught up on the base of the head on the top side against the lip at the base of the penis head, pushing on it.

seem normal or was i doing it way too wrong? do you guys think its worth it to start using again?
