Preparing For A First Device

After a long stretch of honor-system orgasm control, my wife has agreed to let me buy a chastity device. My first thought is to go with silicone because it can be cut through in an emergency. It’s unlikely, but I wonder: what if I get hit by a bus and end up unconscious in the ER without any key for you? What would the doctors do when they see some locked metal cage tightly encasing my genitals? “Nurse, bring me a blowtorch… no, wait, let’s use a circular saw.” It doesn’t bear thinking about. So, initial online research suggests that the silicone Birdlocked Neo will fit varying sizes and shapes. Does it make sense to just order that one and see how it works? I don’t seem to notice this model mentioned often in this forum. What do you think?
