Was coming here to make this same comment lol. Not just wasteful, but inefficient and insufficient!

I got my first bidet at an apartment several years ago. Some people thought it was weird and my roommate always had a funny line he would use to change their minds:

"If I took a piece of poop and smeared it on your arm right now, would you just take a thin a piece of paper and wipe it around a few times? NO, YOU WOULD WASH IT OFF"

This is the bidet I recommend and give as a gift to the bidet curious: https://www.amazon.com/Luxe-Bidet-Neo-120-Non-Electric/dp/B0...

I of course now have a 300 dollar one with a heated seat and warm water, which I can't recommend enough.
