Cage in panties. Advice Needed.

Hey Sissies,

My chastity cage doesn't fit in my panties. I'm not sure if it is because my sissy clitty is too big (7.5" erect), the type of cage I have (CB6000), or the panties I have (a variety from g-strings to bikini bottoms), or something else I am doing.

Does anyone have any advice or tips?
