Yes, I think so. I think I could probably safely go the next size down on the ring though. I think I got the right length of cage (for a starter anyway). I could do to use the stocking method of getting into the cage, as my foreskin just kept pulling back. I was looking forward to the experience, but I wasn't at all prepared for how good and exciting it would feel - takes your breath away!
Just for your info, your missing the top plate off your ring, this will make it more secure, and also the spacer of your locking pin, this will hold it all together more rigid, and prevent pinching, and enjoy!
Thank you for noticing - I think I got rather carried away in the excitement of finally having my first cage. It's definitely all put together properly now, and completely snug and secure I appreciate the guidance.
