Introductions discussion

Hello, I’m a newcomer here and my name is Rivkah. I am a transgendered bisexual woman aged 35, looking to be owned and secured in lockup. My ideal lifestyle blends the Arabian Harem with Gorean traditions. I adore everything Arabian (hookahs, music, incense, faceveils, harem attire, etc.) as well as intense bondage and chastity gear that keeps me from using my own body because it belongs to another… I’ve been on hormones for some time now; currently sitting at a 38 B cup with aspirations of reaching a C. Recently bought two devices. One is a cock cage and the other a belted version.. They are generic knockoffs but function perfectly.. The belt style is my favorite. However, I have some questions about them that led me here.. The belted chastity device came from an eBay seller in China. It was brand new and sealed; actually, it needed assembly which proved quite tricky due to missing instructions. I think I put it together right but still have a few doubts…

1. What’s the ideal tightness? It needs to block access or stop anything slipping out without cutting off blood flow too much. Right now, one finger fits behind and I might squeeze my penis out if I try hard enough, yet everything feels incredibly snug…;)
2. The rubber edging keeps peeling away from the metal rim even after securing it.. Is this typical? Any tips to stop it? For now, that covers my questions.. I’ll likely think of more as time goes on… Excited to hear back and learn… Blessings, rivkah
