Well, the puppy is sort of new to chastity, knows a bit about devices and such, but is on first real stint with RL experience with his new Mistress sooo... Will start off where am now. (also, being trained to be her puppy, obviously hehe) About a month ago, I ordered a CB-6000 as my first device, it came, and we did various configurations for the first couple days trying it out, I do like it, it was comfortable for the day time however... Every night, when I got soft in sleep, the head would get small enough to pull out through the entire device through just normal tossing and turning in bed, and I'd wake up in extreme pain with the device being yanked down on, again from tossing and turning. Tried everything, the only way it worked at all was with the 2nd smallest ring, but in that case, within a couple hours it started cutting off blood, to again, a terribly painful level. So, went back to the drawing board and decided to also order a KDS-G3, that arrived last week, and I had a go at it, tried everything, and it didn't solve the problem. I could still pull out, but instead when I was in the cage, with any of them but the largest, it would cause edema on the head. So! We're giving up on the 6000, I spent another day playing, trying to get everything to work, and it just won't. So... Moving forward, and suppose information wise, it's obvious I'm a grower, when soft... pretty small, anyhow... We've been looking at options, and so far think I will be ordering a birdlocked in the next couple days... I've read all the bad reviews, and all the good ones, but any further input would be really appreciated! Thanks! Woof woof!
