Chastity device discussions and reviews discussion

Is anyone else wearing a completely sealed steel contraption such as the Steelheart? How does your internal diameter compare to your flaccid one, and what do you suggest regarding that measurement? I’m currently sporting a Steelheart with a 40mm width; my glans reaches up to 33mm while my shaft sits at 31mm. For a new unit, the choices are between 35mm and 32mm. Although 32mm looks like it would keep me in constant contact with the cage walls, I worry that 32mm might be too narrow for proper drying after bathing. Do those of us using sealed devices have any thoughts on this?
