Tips for Fitting Your Chastity Cage

I picked up the standard size model that includes four rings, so I expected a bit of trial and error to get the right fit, but it’s no big deal. I’ve read that if you can slip one finger between your knuckle and the base of the ring, it’s loose enough; yet two fingers means it might be too loose? Does that sound right?

I’m also wondering how close the chastity cage should sit against my pelvis. Should it stay snugly pressed up against it constantly? Right now, mine sits a bit lower on my shaft, and erections naturally push it further away from my body. Does this suggest my ring is too loose? Also, when I wear the chastity cage, the head of my penis doesn’t quite touch the end of the tube; does that mean I’m undersized for a standard model while flaccid? Would a mini or nano version be better?

Any advice would be appreciated.
