Chastity and orgasm denial discussion

Hello everyone, I’ve been watching the forums for a while without posting much, but I could use some advice. My partner and I bought a Gates of Hell device recently for shorter sessions, and we were both really pleased with it. The issue is that my size makes it less effective… even when fully erect, I can just squeeze through the fifth ring, yet the real problem is there isn’t much discomfort, which was exactly what we wanted. Has anyone found a smaller version of Gates of Hell suitable for us, and where should we look?
