A little confused here as well. I think you will have your whole sac tied off in an ok grip up near where it ties to the wang, yank your duder down with the other hand while you stretch your nutz up..in order to go up, because your root is in the way, you obviously have to either go left of the shank or right of the shank. I think to keep things even, be best to alternate sides..am I getting this right? I understand the sac down wang up part. Just unclear on the other.
