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.
Pfft, real upscale bidets also have lights, background music, and spray your bottom with your choice of scent when it’s done (Cherry, Vanilla, or New Car Smell).
