I didn’t use to either shower or bathe but it was a mental health issue: I went though both depression, which didn’t help, and I didnt have good showering habits due to being kinda aquaphobic. If water hit my face at all I would think I’d die (pretty dumb I know). Nowadays I bathe pretty much daily. Having a detachable showerhead helps a lot so I don’t have to deal with water on my face.
