ouch.

Maybe capris or longer type shorts that are more of a cycling short style? I know there are running places that carry "compression" style shorts of various lengths. A long time ago when I ran, some of us had chafing problems. I was very young but I remember the coach telling my mom to get me longer shorts. That seemed to solve the problem.

That has to hurt. I have some capris that have a seam that rub when I do longer runs. I tend to not feel it when I run but when I get in the shower...
