Wisdom is learning from experience.
When buying your lock to hang from your penis, make sure to get the kind with the longer loop. I just got a new lock and forgot, I had a long loop one before... got shorter one today.
Ouch!
So the long loop allows blood to flow out of your glans. Same reason why [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]Size Genetics[/words] base ring has that bump on one side... Your corpus spongeum (sp?) is thd underside one of the 3 penis tubes that fill with blood. In erection, the outlet veins get pinched off inside your base allowing all 3 tubes to backfill with blood like balloons.
So if you put [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]
SG[/words] base on upside down, or if your biker lock has a small loop, you (I) can get a pinch off of the CS cavity which causes penis swelling... in my case just the glans.
This hurt like a motherfather! On top of that, my [words=http://www.mattersofsize.com/forum/showthread.php?44-Ace-Strapped-Jims-Joint]ace bandage[/words] got pinched into the lock and it jammed. I couldn't get it off. So I had yo carefully cut my [words=http://www.mattersofsize.com/forum/showthread.php?44-Ace-Strapped-Jims-Joint]ace bandage[/words] and pull the pieces out and off my penis. Then squeeze the blood out of my swollen glans... then slide the lock over my painfully sensitive swollen penis skin and glans...
So what we've learned here is...
Don't buy this lock:
c=[]
Buy this one:
C==[]
Class dismissed.
