Admittedly, it doesn't happen to a lot of people, but you don't wanna just wake up one day to discover that one of your balls just twisted and asphyxiated itself cause you didn't properly check them in the shower.
(Also it hurts like hell. I once had a partial torsion and I felt like someone slapped me in the balls but for like an hour or so.)
