We gotta be careful of the 'footprints' we leave at notels. Flushing condoms isn't always practical, but neither is throwing them in the trash. If nothing else, ladies should be dumping their own trash, at least the bags with the used condoms in them. I try to give pointers to obvious newbies, but they just blow it off, like ehh. I personally don't like leaving a bag of my nut lying around for someone to find. Looks too much like...oh, evidence. I don't want to have to explain why my nut is in a bag 30 minutes or so away from where I live.
We all gotta be more careful.
