When I need it, I personally find taking a shower to be a bother. I'm a large guy, both chubby and quite tall, and my shower is small, like, very small. It becomes a hassle and is uncomfortable, and the water pressure is piss weak. I use my hair and forehead as a warning system, if I touch my hair and my hands feel greasy, or my forehead feels greasy to the point where I need to wipe it off, I take a shower immediately.
