Bro, since I haven't slept yet tonight(last night, I mean), I may hit the international keyboard changer on my idiotphone and post in one of the 37 other languages that I'm fluent in.... So don't mind me... BUT...
My advice would be to repair your SACK, at this point. I'm sure you do care about your joints... But I'm even MORE SURE that your significant other(s) really only care about THE JOINT!
Did you ever watch BRAVEHEART with Mel Gibson? Did you see him get his SACK hacked off and disemboweled?? Did you witness the helpless look of despair whence he realized that even all the test in the world wasn't gonna make HIS cock work again???
But you have a choice, sir knight... The sack may be retreating, but your jousting stick is still fighting.... For you!! You've already turned your SACK on him.... DONT TURN YOUR BACK ON HIM TOO!!! Up the test, drop the deca, get the Prolactin in check and DO THE RIGHT THING.... DO IT FOR ME... DO IT FOR YOU.... DO IT FOR SIR WILLIAM WALLACE!
