There's a certain freedom in the shower... for a brief while it's all yours. I mean, you're nude anyway... you don't care... you have warm, massaging water... it's only natural to want to go with it.
Though, I tend to be meticulous in the shower when it comes to cleaning... so I have no worries.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
