Who wiped Henry VIII's bottom?

It is true that Henry VIII did not wipe his own bottom after he had grown too fat to do it himself comfortably. However, this was not done by a slave or any servant; as a matter of fact, the "Groom of the Stool"was an enviable job, filled by only the most trusted men, who in fact were aristocrats themselves.

The reason it was a desirable job was that you had access to the king when he was most at ease and most vulnerable. You would also be privy to his most private expressions.
