My wife purchased a Rigid model 1 after she had me gauged up to her target size. It is a 70mm tube length and comfortable but she was not pleased with the amount of free movement that was inside the tube. She then ordered the same model cage but with a 60mm tube. It was comfortable but i am uncut and she ordered both cages with the "S" hook to accommodate foreskin with a PA piercing, I kept getting edema at the tip where the foreskin meets the hook. I went smaller as Rigid suggests and i dont think i went too small. Any advise is welcomed.
