Since the day I moved to USA, I still can’t get used to those horrible fixed shower heads poking out of the wall with no way to adjust them. First thing I did is bought my own proper big flexible shower head with douche attachment. And yes after a lifetime of bidet or washlets, I had troubles to adjust to wet wipes etc. to maintain cleanliness.
However, it takes only couple of minutes to clean yourself after using the restroom even in standard American bathroom. All it takes is to make it a habit.
All that being said, I’d never let that stop me from enjoying rimming. Just take some time to get ready. It’s one of the hottest and intimate things out there for me. And yes it’s art and talent. Not everyone can rimm good but if you can, you’re god in the bed. At least for me.
