Yikes, you take showers quite consistently. I remember as a child that I HATED showers. I would stand in the hallway, reach around the doorjamb and turn on the shower, only to be frightened by the loud sound of the water (still frightened by it, reminds me of the Velociraptors from Jurassic Park), and to run into my bedroom and hide under the blankets.
I'm very tall, and even as a young child I was too big for baths. So, when I could get away with it, I wouldn't shower. This led to not brushing my hair or teeth as well. I used to take a shower about once a month, if that, and never brushed my teeth, leading to my current dental fiasco. I'd much rather shave my head then brush or wash my hair, even though I want long hair.
I'm also disgusted with my own visage, as well as body hair in general, so aside from using the bathroom (would still rather use a stump), I stay as far away from the thing as possible.
Changed somewhat recently, as I grew up I've started to want to be clean. But sometimes I'm so wiped out by work that I forget, or I never get around to it when I do remember. I've improved to weekly, but that's not good enough.
Oh, and when I do shower, I only ever do my crotch, pits, and feet, and sometimes hair, depending on the length. Whenever I try to do the rest of my body, it takes too long, and the hot water makes me feel like I'm going to pass out. Can't take cold showers at all.
