This is a really stupid question but how are these supposed to work? Do you just shove it under your butthole and spray away?

I visited Dubai once and wasn't sure how to use these lol. One time I tried it and it hydroblasted my asshole. I told one of the other foreigners I was with and they laughed at me because they said that was just to spray down shitstains on the toilet. That happened at the end of my trip and I never got to ask someone who knew wtf they were talking about :(

So now I have no idea wtf they're for.
