I used to do that as well pac!
I would try to make it look like I'm itching my nose or about to sneeze.
I've been worried about the length of my scrotum, lately. It's been sagging more and more. It's become so bad that I'm starting to hurt my balls if I don't sit carefully enough. I mean, even when I'm already seated, just moving my legs a little sometimes makes me end up hurting myself. It was especially bad during my exams last week because of the little space I had when I wanted to cross one leg over the over.
TMI! but can't unread now.
did you even do a bit of google searching to see whats the cause's of sagging balls?
