So my gf and I has been indulging in chastity play for a few months now ,I have CB6000...and have been locked a few time.....but mostly it last lasted a week and half and my average time 4-5 days.. & it has been really nice in terms of fit and like it never felt more than a slight uncomfort or pain which is expected.....this was for mostly as punishment and it has really prevented to orgasm.

Now my gf has expressed we should get the smallest cage possible or flat cage.....not as long term device but when she wish to punish me little more severally and wanted like she could make me wear it for few hours.....like for a session

Now what I ask is will it be fine if we use the small device this way....or its gonna cause some problems...
