I have a stainless steel cage from kidding zone with a 43mm ring and a 47mm ring. I started out with the 43mm which I could only wear for 1 hour or less usually so I got the 47mm. When I first tried the 47 it was a little too big and caused my balls to painfully slip through anywhere from 1 hour to 1 day later. I bent the alignment pins slightly to make the ball gap smaller and now there's no more ball slippage. My new problem is after wearing the cage for awhile my balls start to burn and I get a red line around my balls where the ring was. My balls never turn color and stay the propper color the entire time. So what the hell does somebody with high tight balls do next?
