Septum/Cord feels flat/wide

I’ve been experimention hanging at upward angles and if I feel my penis under stretch the tough internals feel wide or flat if that makes any sense. Just wondering if this is normal and if that info could be used to make hanging more effective ie; hanging over the leg, different angles, etc.
