Walk bow legged like a cowboy.. keeps things from rubbing.
I've feltyour pain and don't have a cure other than to either shower or bath (in an ice cold creek)a time or two or be liberal with the wipes. I take some spray on anti scent which knocks down the stank somewhat on used clothes.. but I've learned that you just can't stay scentfree up in the mountains after several days or more of serious hiking... use the wind and stay upwind of your buddies!
