You know this topic always comes up this time of year. I have often wonder what other women do in this situation. I usually am half dehydrated most of the time so I usually don't have to go.
However, I went to a race once that had no restroom before the race so had to go out back. Anyway so nothing to wipe with and it still manages to run down your leg no matter how you stand, sit, squat whatever. Anyway so pull up the shorts and realize I had gotten then wet from pulling them back up to quick I guess. That was a gross feeling, but you get over it quick when you are racing.
But one thing to think about when purposely wetting shorts, if you get an open sore or abrasion before it dries, it is gonna hurt.
