My wife and I have been using a CB-6000 and it has been great. One of our favorite things to do is for me to wear a double strap on with a large dildo and my caged cock. When she gets close to orgasm, slip the chastity device so that it is inside her and I use a vibrator to cum while in the device. The orgasms are unreal. Then I switch back to the harnessed dildo and bring her to orgasm. Also, we really like pegging from time to time, the feeling in chastity case is beyond intense. Problem is, my penis is short - 5.25 inches, but the circumference is large - about the same size. To make matters worse I have a tiny, tiny flaccid size and the CB-6000 is too narrow. On top of that, I have a thick scrotum, so I need a little more room than most. I'd love to find a comfortable, long term device. Based my description, if anyone out there has any good ideas, please let me know!
