So after trying a CB-3k and 6ks, I have found, as most of you have as well, that I can pull out of either device when flaccid fairly easily. The POI don't prevent pullout, they just cause pain during arousal. Doesn't matter what size I use. I have also tried both KSD devices. The G1 and G2 don't prevent pullout for me, they just make it more difficult. Not to mention the G2 can cause a lot of pain and damage. The G1 is just too tight of a fit, and I don't like the idea of a ring constricting me constantly, it just seems like a recipe for pressure sores, and the cleanliness issues worry me. Due to the above, I went and got my frenum piercing. It has been just over a month, and it is healing nicely. Now I want to use it. I have taken a look at some of lori's tubes, and while they are quite, nice, they are also a bit out of my reach price wise. So now I have set off with a goal to find a method of securing the 6ks by using the frenum piercing. A few ideas have come through my mind, but I don't want to start drilling holes and investing in jewelery and locks before I get a really good idea of what might work. I also am coming here with the hopes that there are people just like me, with my same wants and needs, who has figured out how to secure either a 3k or a 6ks by using their frenum piercing. So far the best idea I have had is to drill two small holes in the bottom of the 6ks that align with my frenum piercing and put a surgical steel lock up through the bottom so that it hangs down. It seems like the pressure would be minimal, and the chances of it getting snagged are also small. There's just the one small problem of figuring out how to get the lock through the piercing while being unable to maneuver anything inside of the cage... I really want to put some thought into this and try to account for all the possible variables before I go any further. I am sure that some of you have been trying to figure out this same exact thing, and I would love to pool all of our ideas together to come up with a completely secure CB-range device. Please comment if you have any thoughts or suggestions or if you have figured out your own solution to this problem. I am desperate for an answer. Thank you for taking the time to read this and providing your valuable feedback.
