I'm relatively new into the topic and having some questions about chastity. I measured my diameter with a string and it's measuring about 60-65mm while being unerect. (the holytrainer page would suggest a 55mm base ring for this size). My penis alone is measuring ~43-45mm fully erect in diameter.
I've a cheap chinese remake of the CB6000 with different rings (49mm, 46mm, 43mm, 38mm, 35mm) as well as a chinese stainless steel device (45mm ring) in my collection.
I found out that 40-45mm rings matches best, while being unerect without cutting of the blood supply and hurting. My problem about that is when I'm being erect, all of the rings but the 49mm ring would be too tight, so it's cutting of my blood supply (in case of the plastic device) or stretching my balls because the penis is pushing forward and they are turning a bit darker. But if I'm using the 49mm ring it's too big while being unerect... so it's slipping down while being unerect and keeps not sitting on the root of the penis. I don't really want it to slip down, because I could easily pull my penis out of the cage while being unerect.
Now I'm wondering which size you would suggest to me and if it's normal to have blue colored balls while being erect and how tight a ring should fit in both cases (erect and unerect).
I'd like to wear it 24/7.
Thanks in advance.
