When K and I started male chastity play (locking), we used a CB-3000. It is a fairly adequate device for its' purpose. It does have limitations though. The biggist of these is that many men find that they can pull the penis out of it, masturbate, then manage the penis back into the device. This would allow the man to masturbate all the while avoiding the detection of his lover. Such was the case with me. Realizing this early on, I tried to devise ways to make it 100% secure. I found different ways to approach that kind of security, but given enough time, I could defeat all of them. It is somewhat ironic that even though I wanted to be able to have a 100% secure chastity arrangement, I did my best to defeat all my attempts to make it so. I then decided to get a Prince Albert piercing. This would definitly be the cure all for security. After getting the piercing, healing up, and incorporating it into the chastity device, it was indeed 100% secure. Alas, this shortcoming of the CB-3000 had been remedied for me. This was all done prior to K and I making acqaintence.
After K became aware of my desire to be in a chastity relationship with her, she was willing to work with it. As she became more and more aware of the benefits, she also became more wanting to keep me locked. Early on in all this, she would often call or send a text message and inform me that she wanted me to lock up. I kept the CB-3000 (CB for short) at my house. She kept the only key to the lock that secured it to me. When she would tell me to lock up, I would at my next opportunity go into my house and install the CB, clicking the lock shut. Often times, she would tell me to send her a picture on her cell phone to prove that it had been done. Since she had the only key, I was secure until we were together again, and then she would unlock me when she wanted to. I say "at my next opportunity" because she might tell me to lock up as soon as I got home from work, the grocery store, or anywhere else I might be at that moment.
This all worked for the most part, but there was a couple of detrimental factors. One is that the CB was hard to keep clean and odor free. No matter how hard I tried to clean it while locked, it would still begin to have disagreeable odors after a day or two. The only remedy to this was to remove it and clean it thoroughly, sometimes using a mild bleach solution to be thorough. Of course, this couldn't be done if K and I were not together. This limited the times when she could keep me locked.
Another detrimental factor is that it was very hard for me to sleep in at night. Us men, we have this natural thing of nocturnal erections. Not good. When trying to sleep, I would wake up in the early morning hours with a very hard erection, like most men. The only way to get relief from this was to go to the restroom and urinate. This was difficult because of the erection. The CB holds the penis in a downward direction, even when trying to have an erection: uncomfortable. I in no way am trying to brag, but when fully hard, my size is being severely squeezed by the CB. This prevents urination since the urethra would be squeezed shut. This was all quite an uncomfortable situation, disrupting sleep severely. K and I discussed this and as a rule, I was not required to sleep in the CB.
I began to look at options. I had seen another device being marketed by the same seller as the CB-3000. It is the PA-5000. The more I considered it, the more it seemed a possible answer to my issues with the CB-3000. I ordered it and soon found it to be much better to wear than the CB-3000. It allows the penis to move in any direction at any time. This allowed for nocturnal erections to be more natural in that the penis was not held down. For me, it made for less discomfort at night and made it easier to use the restroom when awakened by an erection. Also, the size of the PA-5000 was bigger, allowing for my size when erect, not squeezing shut the urethra, allowing urination. The 5000 was also vented much more than the 3000 and is much easier to keep clean and odor free. I have worn it four consecutive days and never had any trouble keeping clean and fresh.
I also ran across another device on the internet. It is called the Kali's Teeth Bracelet. It is a vicious looking thing. After showing it to K as a mere point of interest, she announced that I needed one. I was a little nervous about that idea. The KTB looked to be severe. The literature said that it was docile when flacid, but could inflict much pain if any degree of erection occurred. An interesting concept. We talked about it and came to understandings: She must always be accessible, with the key, when I wear it, and I do not ever sleep in it. After much discussion I told her that I would make her one for use on me. With in the next few days, I purchased the material needed and fabricated a KTB to put on my poor penis!!! That is going to be an interesting journey.
So now, I have three devices: CB-3000; PA-5000; and a KTB.
