Chastity device reviews discussion

Hi there. I don’t want to sound like a braggart in my debut post, but I’m planning to buy an item and am concerned about the fit. My penis measures 4 inches (100mm) while soft, which feels pretty high for those stats. Do you have any suggestions? The curvature looks quite pronounced on this model, though it seems maxed out at just over 3 inches.

Like many others, I’m also worried about how secure the lock is (specifically avoiding accidental dislodging) and keeping things clean.
