CB Range discussion

My CB6000 has finally arrived and I’m quite annoyed because it doesn’t seem to fit properly. The biggest ring is just about manageable, but the pins press hard into my skin due to how tight they are. The real issue is that my girth is slightly too broad for the plastic shaft; even with plenty of Ky lube, I can’t slide it in all the way. My skin bulges out through the vent holes before I get fully inserted. I’ve attempted this both flaccid and semi-erect without success. Also, the eyes on the shaft aren’t aligning with the pins because my girl is bunching up and getting pinched.

I never thought of myself as big, though my mistress says otherwise. I’m really at my wit’s end with this CB right now. Has anyone else dealt with similar fitting issues? If so, what did you do to fix them? Hygiene is another worry; if I manage to get it in, the fit will be like a sausage squeezed into its skin, leaving little space for cleaning—not even an ear bud would help.

If it turns out I just don’t fit this device, could anyone suggest alternatives with a wider girth?
