Introductions discussion

Greetings, I am thrilled to have discovered this forum and look forward to spending plenty of time here. I feel a little nervous since I’m extremely new to the world of chastity, but your posts put me at ease enough to “come out” into the open. Please forgive any awkward moments due to my lack of experience. My wonderful pet is thrilled by the prospect of wearing a device. I enjoy taking charge of his pleasure and making him wait for permission to orgasm, yet we have only experimented with verbal instructions and temporary restraints so far. He is wonderfully obedient… but both of us feel that adding a chastity device would “raise the stakes” in a very delightful way:). Now for the challenge. It seems that my perfect device doesn’t exist, and my preferences don’t quite match those of most members here… I’ve been searching for info intermittently for months with no luck. Before I give up and visit a local plastics store to build my own cage, I decided to ask the experts:). I hope someone reviews this somewhat complex wish list and tells me what’s feasible, and where I should begin. I realize not everything is realistic, but I appreciate your input on the doable parts. Many thanks! -My ideal device would allow him full erections, while remaining comfortable and suitable for public wear. We spend a lot of time together, and his bits get plenty of exercise when I’m around;), so I’m not overly concerned about “accidental” orgasms - just want to stop him from masturbating and reinforce “hands-off” orders. I love the idea of him being able to get fully excited, but (mostly) unable to do anything about it. Also, he adores moderate CBT, and I’m worried that discomfort might make it hard for him to lose an erection - I can see this becoming an emergency while I’m away. He’s slightly above average in size, so using one of the CB-xxxx devices would not allow for a full erection, as far as I know. -Made of plastic, well aerated and easy to clean. He passes through metal detectors at work, and his living situation doesn’t require elaborate cleaning or toilet routines. I envision him locked up continuously for no more than 2-3 days on average, perhaps up to 5 if he misbehaves… Any thoughts? Again, your advice is greatly appreciated!
