Is it normal i don't wash my back when i shower?

I wash my entire body, except my back, when I shower. All the stretching and trying to scrub that hard to reach area just doesn't seem worth it to me.

It's almost a stressor.

Like, I take showers to feel better, not to have a 3 way fight between both arms and my back and I feel like if I struggle too much, I'll slip and break my skull or something, so I just say fuck it and skip the whole back area altogether.
