I'll use one or possible two leafs of toilet paper to dry myself if I'm at someone's home. In my own homes, just as one has His and Her towels we keep Mine and Your bidet towels, which regularly make it into the laundry every day.
My second mother (a 97 year-old Japanese American neighbor who took care of me when my mother was making one of her monthly ritual visits to a hospital) recently built herself what I like to refer to a Castle Starter Kit. However, in her case, it's pretty much an all out giant mansion. In her bedroom she has a Japanese manufactured all-in-one toilet where the lid automatically lifts up and the damn thing plays soothing music as she does her business, blow dries her ancient naughty bits, and finishes her off with a light spray of something that smells like Jasmine. When she's gets up the seat automatically closes. It was about $4,000. For seniors (which I will be sooner than I hope to be) this seems like a great way to take care of and maintain personal hygiene with dignity. Old folks are prone to poop and pee issues that are simply part of growing older.
As I mentioned in early posts, I grew up with a bidet in our farm house. When I moved back to the USA to care for my father for a couple of years before his death, he had major problems with bladder cancer and an enlarged prostate. He also had a toilet and bidet in his bathroom. I was very proud of the fact that my father, unlike his posse of 80+ year-old buddies, never once smell of old man pee.
It's something to consider.
NOTE: The "save a tree" remark is something I stole from my plumber, Jacques Dupre, who came to my rescue many times as I renovated a painted lady near Buena Vista Park. His business card read: "Jacques Dupre, save a tree, install a bidet."
