Pumping Problem
I have a little problem here with pumping.. Not really a problem, just more of a question/concern. First, when I pump, I have the joel kaplan pump with the 2” diameter and I usually pump at about 5 hg.. Anyways when I pump my scrotum gets sucked up into the tube expanding to the whole circumference of the first 1/4 of my penis. Is this normal, and if not, what can I do to stop this? I’ve tried many different positions but when I get up to 4-5 hg, the scrotum gets sucked in everytime, it doesnt really bother me, but is this going to be detrimental to my gains or penis health.. And second, what exactly is the “donut effect” I’ve read alot about it but I can’t seem to understand quite what it is.. Can someone please help me with my 2 quesitons. Thank you
