Think About It. Gotta go. One or two? When I was young we “went” in the “outhouse”, I suppose to “relieve” ourselves, with a Sears catalogue to relieve ourselves of 
“it”. Of course for night the “pot” under the bed was not for smoking and not to be confused with the can-o-py over the bed. A sturdier receptacle was sometimes called a “thunder mug”. Don’t ask me why.
In grade school we went to the “basement” since that was where you would “go” when urgently chosing the number of digits to wave, signaling everyone the nature of your distress. Moving to a newer home I discovered the convenience of John Crapper’s invention. For a while “going to the “John” was alright, but “crapper” sounded too much like what you were going to do. So we went to the toilet (borrowed from the French “fete ma toilette” having little to do with what you’re really planning. It was then generally decided that going to ” the bathroom” would be a more acceptable expression even if you couldn’t necessarily take a bath there. When that became improper in proper society, “the powder room” or “little girls/boys room” worked, especially on a date or in a restaurant.
Nobody anywhere wants to face the facts, although that does sound awkward. In England you find “the loo” (an adaptation of the French for water). In France you go to the W.C. (water closet) where you give rather than get. Of course on busy sidewalks there men have access to a”pissoire”, but that word is little close to what we now use for being angry.
We haven’t yet sat on “the throne”. And we will ignore things like “dropping a deuce” or (heaven forbid), discuss a “golden shower”.
If you’ve rested in a public “Restroom” lately you may have found the “porcelain” was labeled TOTO. You’ve got to wonder why that brand name wasn’t registered sooner.
Not having aged with the language can cause confusion. A woman shopper recently intended to cook a stew in a “pot” she had found in an antique store. changing her mind for some reason when a friend discussed its history.
Where do we “go” from here to pretend we don’t have less than pretty body functions? Maybe the choices of new words for old business aren’t exhausted, but I am. So before I’m accused of being a “potty mouth” I’ve Gotta Go. Think About It.
