Pretty sure astronauts do too. I remember the weird astronaut love triangle incident where some astronaut lady who was in love with some other astronaut drove nonstop cross-country with apparently a BB gun and wearing a diaper to do God knows what to the guy. It was explained that wearing a diaper during spacewalks was routine for astronauts, so it probably seemed like a reasonable and convenient thing to do for her, rather than crazy and outlandish as it seemed to most regular people.
