CB Range discussion

Hello everyone, I’ve just started my journey into chastity and have been wearing a curve for two weeks. The fit feels slightly oversized, but I’m unsure about the ideal amount of room. Since I am such a grower, I wonder if measuring while flaccid is actually the right approach. When soft, I measure 2.5 inches from the base; when fully erect, that number reaches just under 8 inches. I haven’t checked girth yet, but in my soft state, the cage barely covers half its diameter and sticks out through the holes enough to cause pinching during arousal. Essentially, I’m leaning towards getting a 6000s model for better comfort when flaccid, though I worry about how it will handle erection. I’d appreciate any insights or advice! Thanks,
