Mature Metal discussion

Hello everyone, I’m following up on my previous thread: I plan to switch from the referenced community page over to a MM Jailbird, Pet Trap, or Watchful Mistress (still undecided:rolleyes: ). The problem with the 6KS is that my cock isn’t very thick and is quite small; consequently, it sometimes “pulls back,” leaving a gap at the tube’s end. Therefore, I want a Jailbird cage that is slightly narrower. The 6Ks length is reportedly 2 1/2”, so I believe I’ll keep that length (or perhaps trim it down to 2 1/4”), but I’m struggling with the diameter because I need to confirm what the 6KS diameter actually is, ensuring my MM device ends up a bit narrower. I welcome all advice and suggestions!:D [Edit] - On second thought, my Wife enjoys teasing me by putting me in bondage. She lies next to me and reaches orgasm with her vibrator before turning her attention to me, using the vibro on my CB for edging as close to climax as possible without letting me cum. She owns a Rampant Rabbit and a small “bullet” vibrator, utilizing both on me. The Rabbit’s “ears” usually sit in the 6Ks pee hole, while the bullet rests directly against the tube. I mention this because we’ll need that capability with an MM device, making me wonder if it disqualifies the Pet Trap (which is currently our top choice)? Thanks.
