> When you hike? I'd have thought doing it in nature would be fine (considering all the animals doing the same) I assume it's because sometimes there's enough brush that you don't want to squat more than you have to, exposing your privates to plants, insects, etc. On top of that, you need a lot less privacy to stand-and-pee than you do to squat: if someone comes across you squatting on a trail without much cover, you probably wouldn't want them catching a view of either side of you. Perhaps it's just not-totally-rational squeamishness, but that's my understanding of the thinking behind it.
