I have the same problem, zoom-zoom. Unfortunately, I haven't found any shorts with a well-fitting chamois, so instead just look for ones without seams. I actually like the Shebeest shorts for that reason, and Gore. I rack this up to my freakish dimensions, like all my body parts are mismatched and came from the second hand bin. Oh well.

For the record, rotating my pelvis doesn't help, and it's not a problem of being uncomfortable while on the saddle -- the issue is with chamois placement in the shorts.
