The wife and I have been playing with chastity on and off for quite a while now. We have been using the cb6000 and 6000s. We have been toying around with the idea of adding something like the POI and just haven't decided what route to go. Being a DIY kind of guy I suggested that we might try to make something ourselves first. I thought perhaps I'd model it off the POI and so I have begun the design process.
My biggest issue is how to attach them to the cage without altercation of the cage itself. Not having seen an POI or anything similar in person I am not exactly sure how they attach. Are they just fed onto the locking post over the spacer? Do they replace the spacer? Thoughts? Suggestions?
