Chastity device discussions and reviews discussion

Hi all, I’m not certain I placed this in the correct section, but I hope so. Recently I acquired a nice new Chinese chastity cage (one similar to that one). Lately it’s been slipping down during showers (even the catheter component). The dimensions of the cage and fittings seem appropriate. I’m considering ways to secure it better without piercing. Perhaps a spike ring or some kind of harness, but I haven’t located any online yet. Does anyone have suggestions?
