Chastity device reviews discussion

I’ve had the Curve, CB6000, Lori tube #2, and a Jail Bird. The dealbreaker for me is nocturnal erections. Did anyone else with those devices find another option that worked? I’m leaning toward the Holy Trainer or Exobelt Extreme; feedback on those would be great. I’ve also thought about full belts like the neosteel arch masterpiece, but my girlfriend isn’t keen on their look. Do any women here think some full belts are attractive while others aren’t? Did you change your mind after seeing a specific one? Another possibility is that the “A” ring is too tight, yet if it’s loose, everything slides down. Has anyone used a larger ring with the KSD or similar models? I’d love to hear about comparable experiences and fixes. Thanks!
