I find that on long rides, my perineal area becomes bruised and often rubbed raw from extended riding in the saddle. I have tried a softer seat but most seats have the padding at the back, not on the horn. I thought it might be because I was wearing ordinary cotton boxers underneath my leggings, and the extra fabric was causing the rubbing, so I switched to padded cycling shorts and nothing else, but still the issue persists. It becomes so painful I have to spend at least half of my time riding standing up, to relieve the pressure off this area. How have other long-distance riders come to deal with this issue?
