I was googling information on sheath cleaning as it's something I know I need to do but am in NO way looking forward to it. I do not know if Jr. has ever had this procedure done. He was fairly tolerant to my cleaning of the nether regions during his bath yesterday but I have not attempted to touch the sheath area.
Just have to share this link:
There are two articles there, the first is informative, the second is a delightfully humorous instruction manual to the process. Worth a read.
