Introductions discussion

Hi everyone, as you can read from the thread, I’m new to all of this. Myself and my “better half” / now key holder stumbled across Chastity. We were never boring and had sex regular, but this has put everything into another level, texts, pictures, inuendos, I’ve been locked up for a while now and love every second. Not knowing much, we picked a short silicone male device which is similar to a cb3000. Never got on with it due to the width of the back bit which fits nearest the groin. Eventually when found a site called fancyafetish. They had a Black spiral cage (see my profile pic). Now the slight issue I/we have.. .. The smallest ring I can fit over everything is the 45 mm. Even with this, when I’m totally flaccid there could be a chance I could actually get my “tadger” out behind the ring, but not my balls. Is there anything I could buy OR make to stop this? I’ve seen an anti pull out ring for a different type of cage, but that wouldn’t fit ours. KH wants me in permanently but has to release me at night (after her orgasm I might add) so that no damage occurs with a unwanted morning glory, once that’s gone I’m locked up again till she’s satisfied and ready to sleep. Thank you in advance for any advice you can give me
