Renaming the Cock

For almost forty years, my husband/ wife has called the alter ego between my legs “fireman Fred.” She claims that when he gets excited it looks like a fireman wearing a bright red hat. Naturally, all sorts of jokes about hoses and fires go around. Long story short, because I slipped up with my words and we recently started experimenting with chastity she has renamed him Mr. Wanky. Now what used to be a powerful figure of respect is just a plaything that serves no real purpose. My wife might well be the most vanilla key holder alive. What caused this? Is there perhaps an age where a key holder renames her nemesis? Has anyone else gone through something similar?
