If you want a view about a CB for a male I can give you my experiences. I too have a great fetish for them. I love wearing them.
I have owned two such devices. One was a stainless steel belt that was made to my specific dimensions. It was secure and felt great as long as I was standing. It put a lot of pressure on the waist and pelvis if I didn't sit in an up right position. It definitely put the cock out of reach but I could have never worn it 24/7 - 365. It just wasn't that comfortable.
I could, however, once I got a hard on still cum with it on by moving the device forward and backward using the waist belt as leverage. The tube itself would massage my cock and the next thing I knew I came. So its design has a little flaw in that respect. For me CB restraint is mostly in the mind and in that respect it served its purpose for not allowing me to touch my cock during masturbation. The stainless steel devise did allow for other forms of pleasure. It was capable of being wired to an electrically unit which would punish whatever part of the lower anatomy you wanted. You could have it shock the cock or you could purchase an anal plug manufactured for the purpose of shocking your colon. That was kind of fun but I got rid of the devise and all its accessories.
Today I own a CB3000 which is a totally different design and a whole hell of a lot more comfortable. I know if I wanted, I could wear it 24/7 - 365. However, with it locked securely in place, I again was able to achieve orgasm by grabbing the tube and moving it forward and back. Even though again there is no way to touch my cock I still was able to cum. Now the rest of the story.
Luckily when I ordered the CB I also ordered what is called the Points of Intrigue with it. They were designed so that it would make it impossible to removed the devise without first unlocking it. I don't have that problem. It stays securely in place until unlocked by me.
I decided to test the Points out for another use - to stop masturbation. Well I tried the longest Points first and when I got a hard on it was such excruciating pain that I had to immediately focus on something non-erotic in order to get relief from this pain, which almost literally took my breath away and not in a good way.
I then tried the mid-length Points and again when I got hard it bent me over and I dropped to me knees in pain. I am now wearing the shortest length of the Points and it still applies enough pain that there is no way in hell I can achieve orgasm by CB manipulation with the Points in place. It is just too painful but at least the CB now does it total job - prevents touch and orgasm by masturbation. I love it and I only use it for self denial because my wife isn't interested in this type of life. Would love it if she would actually control the key.
I should mention that both devises forced me to sit down to piss. A little humiliating but part of the turn on of wearing a CB.
My thoughts, thanks for listening. I'm glad I found this site. I don't feel so out of place here. It's nice to have a place to converse about such subjects and feelings.
