Though if you use too big a plug, they'll simply howl louder.
It didn't take long before business was booming. The rectal dilators even evolved with time, first fashioned from hard rubber, then Bakelite (an old-timey formaldehyde-based plastic), and finally aluminum. They also varied in size and came in sets so that you could acclimate, but once you decided to use a dilator, there was no turning back. Like ear stretchers, but this time for literal assholes.

Skepticism for these laxative dildos quickly leaked out of the media, but the government was too backed up to quickly pass any regulations. Public access medical devices as a whole were not regulated by the FDA until 1938. Two years later, the administration finally called shenanigans on Dr. Young's metallic butt-corks, and they were banned -- not because of the health risk or the whole illegal sexual arousal but simply because of false advertising. Since Dr. Young had made the weirdly disprovable promise that if you used them you'd never be constipated again, even the courts in those days agreed that such a claim was nonsense. They clearly thought that he was stretching the truth. You could even say that his story had some gaping holes in it.
