Copying the text from another comment i made here:
I have a standalone bidet, not the toilet bowl attachment, which is basically a mini sink, and it works like a sink in that you can regulate flowrate and temperature with the handle
with this kind, you have 100% cleanliness since you use your hand to clean everything, and after it there's a mini-towel for each person, usually in a towel rack near the bidet so no-one gets confused, and usually in a smaller size then normal towels.
If you're worried about the idea of using your hand being unhygienic, rest assured, there's a radical invention called washing your hands afterwards, which, by the way, you should do anyways even if you use toilet paper.
