I bought a solid ring chastity device (ring size 1.75). I have been in the ring and cage for 8 days and all of a sudden one testical pulls back through the ring. Why is it doing this, especially after that many days? I have 2 different devices one is the CB6000s and a hinged ringed device and both rings are 1.75 and are very secure. I really like the solid ring! HELP!
