Welcome to the party!
I've worked on chastities for years and found that a piercing is the way to go for the real chastity experience that you can wear to work, everyday life etc. without a full belt. Here is a link for steel tube designs http://www.stockroom.com/gear/chastity/ that would work well with chastity, especially a PA. Put a lock through your PA ring and through the cage bars. Also check out CM member Vad for some top shelf work!
I have a frenum style that is actually a bit further away from the head, it is in the thick skin of the circumcision scar so that migration won't be a problem. I have had a CBR for eight years now, no problems at all. I have gone weeks without the chastity being removed, and months without it being off except for play time! This is something you can do for real if you really want it!
My own chastity does not tug on the piercing, there is a rod which slips through the CBR to keep the cage from being removed. The rod and the cage can move somewhat on my shaft to adjust for clothing tightness, activity, expansion when aroused in the vanilla world and cannot reach down to adjust it. Latex coating (not shown, old photo) helps keep the cage from slipping down when asleep (if not wearing briefs) but I can add a waist chain to help support the device if I want. That is also comfortable for when I am naked except the cage, for showering, giving an erotic massage, etc.. I do not like a tight sack ring like the CB series, I expand too much for that sort of design. With a piercing, the sack ring does not have to be tight to keep in secure, only tight enough to keep it from slipping down and pulling the piercing.
I like that in my cage I can pee standing up so that I don't have any trouble at work with needing to hide modified bathroom habits, another reason I did not want a ball trap ring or a full belt. I enjoy "manly" activities and hang out with guys who go camping and work on cars for fun, so I needed a device that did not compromise my active lifestyle and would let me pee behind a tree. The only things I avoid now are aggressive bicycle riding and surfing... the cage puts dents in a fragile surfboard (the wife hated when I went surfing, I think she liked chastity for that as much as anything).
The Lori's tube really caught my eye when she introduced them, but back then she was using a standard little padlock. I have never felt that was secure enough for me because I have lots of tools, so I developed mine with much more secure lock using a double sided key. Now Lori has the circular key locks which you can't cut with bolt cutters, very intimidating! If I did not already have my cage, I would order hers since it is so easy to wear to work and play. All my experiments with belts, for both boys and girls, convinced me that a butt strap or chains were not suitable for sitting in meetings, especially if the chairs are made of wood! ::clunk:: For the Loris, you need at least an eight gauge, but might as well get a six. It won't hurt anymore. I got a ten and regret not going bigger.
Way back, Centurions sold a cock collar that secured with a piercing, but that was way before the internet and I have only seen it in musty old catalogs. Lori's concept is not new, but very well done from what I can tell. The main disadvantage I can see with the Lori's is that I suspect it takes a bit of effort to install. I think that putting that pin through a piercing while in the tube would be difficult with only two hands. That's why I made mine so that the CBR stays in and the cage locks to it. I thank a story on Altarboy's site for that design revelation, it made long term wear possible for me. My keyholders have agreed that being able to put it on and off easily was the most important aspect to their enjoyment - if they want what is inside they don't want to be discouraged by the process.
I fear needles, but was determined to do chastity so my SO/Mistress drove me to the piercer after I had a few drinks. She let us use a blindfold and cuffs behind the chair during the process... since I could not see what was happening it was no problem at all! Also I like the mystery of the CBR just being there without seeing how it installed. A touch of epoxy makes it impossible to remove once my cage is locked on.
My cage is now seven years old and has done everything with me... swam in the ocean (with tape over the key hole), been in a roll-over car wreck, worked construction, been hit on by gals at parties, everything. In spite of what some inexperienced people insist, you CAN make this very real in your life and I feel a piercing is the most important step. It took me over three decades to make it happen, I built a lot of things that did not work, but the only failure is quitting. Go for it! BTW, the pain is really nothing, I have had more pain from removing a splinter then I did from the whole piercing procedure. Worst part was the first week of washing it with soap in the shower, but really nothing to be worried about... the thrill will offset any discomfort!
I am about to begin an extended period with a Chastity Steel belt, this should be very interesting! My cage discourages erections because it can get uncomfortably tight, the CS-100 lets me get fully hard but I cannot get any sensation of touch... in my limited experience with the CS belt I can tell it is going to be one heck of a ride! I have "foolishly" committed to a full month of solid chastity to start sometime in the next month or two... don't know exactly when it will start but I am really looking forward to the whole experience! I have worn the CS for a few days at a time already, I love that it does not have a back strap so it is easy to keep clean. I flush the tube with a baby wash bulb each time I pee (yes, sitting down) and rinse well in the shower, no smell or rash problems. A few drops of mineral oil after showering helps. This is the best full belt in my opinion, but I have l have only worn three belts so far and not a Gothels or Access Denied.
If you use a metal tube like the link above, I have an idea for an add-on security device that would work with a frenum instead of a PA. This is something that could be used with a captive ball chastity to prevent pull-out, perhaps Vad would make them, I don't have a work shop since getting divorced. If there is interest, I might share the idea, it is actually very simple. I have stopped developing these things since I built the one I wear now, it has done an excellent job of keeping me locked up for the past seven years while I have had an enthusiastic keyholder.
Hope this advice helps you to realize your dream! Go for it! If you would like more of my thoughts about this, you can send a personal message to me. I have invested many many hours/years into this pursuit and may have be able to help others with my experience. Note, I will be traveling much in the next week and won't be on here regularly so if you write please give me time to respond in detail.
