Look, nobody wants to talk about it, but it has to be addressed. What happens if you are stuck out in the middle of nowhere and you don't have any toilet paper to handle your business? Well, you have to wipe with something don't you?
Well the guys at Sigma 3 Survival School addressed it in the following video. This is not always addressed in survival manuals so pay attention!
I think the most surprising thing mentioned is a smooth rock! LOL!
If I'm just going on a hike or a camping trip I think I'd rather bring some Coleman Toilet Paper thank you very much, but if it runs out this video has some very helpful information.
