Not only will a bidet save you on toilet paper, but you will actually feel like you have a clean butt after pooping. Initially it feels weird, but after you get used to it, you won’t want to poop without it.
BTW in case you are wondering: yes, you still need toilet paper to wipe the water off. But it is a small amount.
No need to wipe dry with TP. Simply twerk your ass until it dries.
I use a butt towel. Just need to remember to move it if any guests visit, lest they start drying their face on it.
