I had a scare. Was not sure if I was going to be a 28year old Lance or Bob Dole. I had gone to the doc, since my "taint" was not feeling good. You know "taint your balls, taint your bunghole". The urologist corrected the slang term. It is the Peranium. He told him that I needed to stop riding, I told him I had to kill him. We compromised on not riding for a while. I got Selle Italia Trans Am Flite, nut canyon. The "cracking" or "racking" does not help. Tip from my doc, ice the crotch post ride if you inflected trauma down there.
