And yes, bodily waste is actually higher on my fetish list than crux is, so I do think about this - it's more or less inevitable, really, if left up there for days. If naked, they can at best hope to wait until few people are around, while any modesty-granting loincloth will be a write-off.
I don't know (anymore than anyone else can) but I've got a wild hunch that on what must be quite a considerable list of complaints, concerns and sheer agonies, the worry over the state of their loincloth must be fairly low, and granted, the fact that as the nails are driven through their flesh and as they are positioned post-nailing the victims bowels involuntarily evacuate must be counted as more than mild embarrassment nonetheless I don't believe that will be at the forefront of the crucified's mind, indeed, they may not even be aware of it at the time.
A visual feast though I'm sure, I don't doubt that the victim was fully exposed at those moments precisely to humiliate them, not so much for the victims reaction but rather to sully them in the minds of what was probably their local community. If you've just watched old Mrs. Smiths son shitting himself in agony as he is nailed to a cross having been found guilty of some heinous crime, it'll be a while before you look her in the eye, and there'll be gossip oh yes.
Crucifixion was a bold statement by whomever was doing the crucifying: We have the power to do this to YOU! We can take you to a public place, in front of your home crowd, scourge the skin from you and nail what's left to a couple of bits of wood like an insect. We can take everything from you and be so bold as to do it slowly and publicly, you will lose control of everything including when and where you piss and shit. I have little doubt therefore that the cruel and devious tortures designed to further exemplify the victim's powerlessness in stark contrast to the crucifiers power would have extended considerably beyond the act of nailing them to the cross.
Perhaps those squeamish about some shit would be better not contemplating what a 1st Century Roman executioner might do to the prone body of the condemned nailed to the cross, especially once they cease their initial screaming and writhing but whilst they still have the strength left to react as the next humiliation and agony is heaped upon them at the hands of those who have stripped them of everything.
