For your big, fat information, I'm restoring an old piece of furniture that needs new knobs to go on the drawers. They are not "butt plugs", nor do they have any known practical applications as such. The fact that you and others in this forum are perpetually trying to turn every possible subject into something sex related does little more than exhibit your hopeless, juvenile obsession with sex, which happens to be a very serious psychiatric disorder. Get help before you hurt somebody.
