In an earlier note, I looked at bath tissue as a substitute for toilet paper or bathroom tissue, both of those serving as euphemisms for some more direct reference to material for wiping the anus clean of feces. Bath tissue is sufficiently indirect that it can take some work to understand out of context.
Since then I’ve moved into a more complex world of wiping, thanks to my not having showers as the grand scheme of bodily hygiene. (My shower is a glass enclosure over a tub, and it’s a big step into the shower — way too big for someone with a new hip implant . So it’s sponge baths and other workarounds.)
There are two needs here: anal wiping again, now to be managed without a shower cleanup; and general body washing (including rinsing and drying), which would ordinarily be done (in the absence of showering) with soap and a washcloth at a sink or basin, This stuff eventually gets a lot easier, but at the beginning the project is much like infant care or elder care, and the cleaning products needed are pretty much the same.
