You dont have to switch but if someone is paying for Proton than they can utilize it for no extra charge

I am not a naysayer so I cant answer that part of your question, but as for what I do with our bidet: theres a little knob that I turn that starts the water spray at my butt, sometimes I might have to adjust the way Im sitting for it to hit the right area. For regular poops I spray for only a few seconds, but for gnarly ones I might do 10-20 seconds with some moving around to cover the whole area. Once I consider myself sprayed, I grab a few squares of TP and wipe to dry. Flush, wash hands, done
