Hello All, Long time lurker, first time posting. First off, I'd like to thank everyone on the forum for the lively discussion and tons of ideas and techniques that have come from this site. What I'd like to share is my set-up for a truly inescapable device that I have been wearing for about 2 months. I completed my first three week lock-up and am 8 days into my next 3 weeks now after a few days of testing and modification. My wife/KH has finally taken a really strong roll in my chastity now that she has a device that cannot come off without her approval (although we have an emergency key in small plastic box that is sealed shut). It has made me more bold in asking to be dominated and tied up and she has taken a great liking to punishing and teasing me. It has really improved our relationship and we are both so happy with the results. I've been through numerous plastic and metal devices. CB6000, HT, and several metal Chinese knock-offs from ebay. I used my experience with those to size and order the perfect device from Aken at Red Chili Chastity. I was able to use a frenum piercing in combination with his adjustable London Tower cage with the "standard" accessory. The piercing cannot be pulled out without the cage being unlocked, I cannot pull my member out the back as with all other devices. I also use the "Osito" base ring, with has small tabs to secure to a belt. This keeps the cage from slipping down and makes erections more difficult (and fun!). My frenum piercing. It's a D-Ring with a special "ball" closure. It's actually a small bar, with dimples in the end and a threaded hole. Into the threaded hole is a small extension post, with a threaded ball installed on the post. The ball and post are super-glued, but the d-ring can still be opened to remove the bar. When locked, the d-ring cannot be reached and opened. My cage. I went for the "Osito" style for the base ring, since I really like using a belt to support the weight of the cage. I'm a serious grower and finding a base ring tight enough to stay in place without cutting off circulation was impossible. The belt allows me to have a base ring that is tight, but not too tight. The cage doesn't sag, and erections are contained by the waist belt. I've been using a stocking on the bottom attachment, to keep the cage from lifting during erections. The standard ring fits behind the cage on the base ring post. As you can see here, the accessory ring has a post that fits into the main cage section. My frenum piercing post fits in-between the front cage bars, and the ball is too big to be pulled between the bars. It cannot be removed with the accessory ring in place. (Side note, what a well made piece of equipment! The cage, not the cock..)(Also, you can see my modification with a small rubber o-ring to keep the bar centered) As worn. The belt supports the cage. Pull-out is impossible since the piercing is trapped between the two cage sections (you can just see the ball protruding from the cage bars near the testicles). Plus, I can get other fun accessory rings that work with a PA, uretheral sound, etc., if I want to change it up someday. All thanks to Red Chili Chastity at http://malechastity-devices.com/ and a great piercing job with a good, deep frenum piercing from Lake Monster Tattoo in South Lake Tahoe, CA. Thanks for reading, please feel free to ask me anything at all! -R ps, we use the security screw and she puts a padlock on just to be safe Also, you can see some white thermo plastic on the base ring post that keep the cage and accessory ring in place.
