What does this have to do with peeing? Peeing outside isn't a crime. Intentional nudity meant to surprise someone can still be sexual assault, these two are not mutually exclusive.

I'm in Asia, in a place with no laws. I won't beat a native person to death for this kind of thing, but if you're "peeing" in front of children, which I have seen multiple times from foreigners here, then get ready. If you're in a city, keep your fucking dick in your pants, just in case your around somebody like me that is shell shocked by too many experiences witnessing pathetic attempts at sexual assault, both "visual" and physical.
My wife has it happen like once a month at least... Keep your dick in your pants around me or I'll hack it off.
