I find it kinda obsessive how much some people shower. Honestly 3/4 times a week is absloutly fine, more the once a day seems just obsessive. Even less if you use a bidet to clean your genitals and clean your feet. Showering daily I think is fairly recent thing and one really based on trying to fit into norms.
The exception is when you have been exercising or (if like me) you are prone to greasy smelly hair.
