Mature Metal discussion

Hi there. I wasn’t sure where to turn for guidance, so perhaps someone here can assist or share a comparable experience. Lately, I purchased the Jailbird from MM’s lineup; it boasts great build quality yet didn’t quite suit me as a chastity device. The gaps between the vertical bars are wide enough that my finger fits through easily, allowing me to touch myself and reach climax in just minutes despite the cage. I tested out the CB3000 and The Curve models too, aiming for something durable, comfortable, and secure. My main issue is that even with a flaccid state being somewhat substantial, the curve model felt quite petite, leaving me searching for an apparatus suitable for longer-term wear without compromising safety. Any recommendations? Thanks! L
