Fresh Questions on Starting Your Chastity Journey

I’m thrilled to have found this community. The most daunting aspect of this entire journey was feeling like everyone else was immersed in extreme BDSM and Kink when it came to chastity. That’s perfectly fine, I don’t judge, but my wife and I have been married for three decades, and I was seeking a way to revive our intimacy and restore my libido. The first talk between us was awkward and tough; she is quite conservative, having grown up in a very repressed household. She has opened up over time, yet my idea of trying Chastity really startled her. We worked through it together, and since that chat we’ve shared two intimate moments where my mind stayed stronger than my libido, leaving me feeling dejected and frustrated each time. I believe this was when it truly hit home: what I wanted was to hand over my sexuality to her, letting her take the reins. So after much measuring, questioning, and research, I placed an order for a CB600S which should arrive early next week. Naturally, I have some common questions…

1. How many couples actually create a formal contract, or is it mostly handled through mutual understanding?
2. When trying on new devices, what advice do experienced users offer regarding adjustment times, checking for issues, and extended wear? I was quite worried about spending money only to find the device didn’t fit well, so I ordered all the extra rings just in case I needed more room…
3. How many men modify their devices for better comfort?, I have a full workshop and can handle various technical tasks; is it normal to round corners and do other adjustments?
4. My wife remains reluctant but willing. I’m doing everything possible to ease her into this experience, any suggestions on helping her gain acceptance? I am so happy I found this site. Thank You.
