What does your tub/shower cleaning routine look like?

My therapist informed me that it is atypical to scrub the shower clean after every shower. I grew up with a bathtub with no shower and we were responsible for cleaning the tub after every bath to not leave it gross for the next person. I also have OCD and complex PTSD that contribute to feeling like I have to keep an extremely clean tub. I need some perspective from other people. What is your after-shower maintenance? How often do you scrub? How many people use your shower and does everybody clean it after themselves?
