Ditch the jeans and get some riding shorts or tights. there was another thread about this yesterday. I use cycling underwear with a lighter padding and then you can wear any pair of shorts or pants other then jeans. The problem with jeans is where the inseams and the fly and center rear stitching come together making a big knot right where you don't want it to be namely the above mention tender area. I was off the bike for two weeks till this thing healed, it was actually blistered.
