A long time ago I was of the opinion every slave should be smooth. I even shaved myself. Overt time however, I have come to the opinion that these a grown males not children, and having a hairy penis is something to be proud of. But I could be coming to that from a natural naturist viewpoint. Then again, were males shaved in the ancient times. I do not know.
I could get my slave to shave again in due course should I decide and rule this is to be so.
