Hi I'm going to order a Holytrainer v4 cage I have a fake one from WISH i think. its the small cage and with all ring sizes, i use the 45mm ring. Have measured with that method in HT website and according to it should use 50mm ring, but when I use that ring one of my balls can slip out with some pain. my cock is: Relax cock from balls: 6.5-8cm - 2.5 - 3.1 " - depends on the day Cock stiff from balls: 16-17cm - 6.3 - 6.7 " - depends on the day Around balls and cock: 15-15.5cm - 5.9 - 6.1 " - depends on the day Would therefore like to hear about what size cage do you think I can use: it stands between the SMALL and the NANO? And whether I would be able to use the original 50mm ring or should I still need 45mm? - whether there is a difference between fake and original? What size do you use in both cage and ring? and how big are your cock? just so I can compare. Sorry for my half bad english Many thanks in advance
