Chastity and orgasm denial discussion

Hi everyone I’m new here and have been in chastity for just five days, with a couple of questions where I’d appreciate some advice.

1. My CB-6000s is locked on tight; after tweaking it the first day, I’ve stayed 24/7 since then. I’m using the shortest spacer paired with the second-largest ring. Sleeping has been tricky (which seems normal), and my erections push everything forward at the base by about 1” to 1 1/2”. I’ve read that a smaller ring might help stop this? I tried a smaller ring when I first started, but it felt too tight. Should I just stick with a smaller ring until it gets easier?
2. As noted in my welcome post, I brought the idea of male chastity to my wife. She was unsure at first but is getting into it quickly. Today she mentioned wanting to buy a strap-on for me. I’m excited yet nervous about that—should I be? I suppose I just need some reassurance… Thanks in advance
