Worried about being dirty... Help.?

Lol, my school went on a camping trip out in the woods for three days. There were no available shower stalls. We just didn't take showers. I'm not a big fan on not taking showers - in fact, I take a shower every day at least, but... I just braved it. If you don't want to use the dirty shower stalls, then don't shower. It won't kill you. It's all part of the experience.
