I was just rollin mine around, doin the usual "search for pea sized balls on your balls" test. On my left testicle, it feels like there's a... tube? Or something wrapped around it. Now I understand testicles are basically big balls of tubes crowded together, but in comparison to my right testicle, the right feels more smooth. The left, as I said, feels like there's a tube or two that's more noticable to the touch. Bumps? No. Hard? No. Eh?
