Thanks Iride, no I don't wear underwear underneath my cycling shorts. I've thought about shaving but the hair down there is sparse and very short and fine. I've also read that the stubble can be irritating and get infected and then there's the risk of cutting myself. Good advice regarding thin chamois, and I also need to pay attention to where the seam is on each of my shorts. I do pee a lot so that's another downside of bibs. Mark
