I have one pair of PI bibs and the chamois seam near my wedding tackle can rub me the wrong way. If I tuck, maneuver, shift, and rearrange to the proper spot they don't bother me. I don't wear them very often and will probably will retire them once I pick up another set of bibs that don't rub me the wrong way. It almost seems like they're made for a more upright riding position.
