Late Wednesday night I got home and saw it there, waiting for me. The box was a lot larger than I expected. I grabbed it and headed into my bedroom, and calmly but eagerly opened it with a pair of scissors. Inside was a much smaller box with a clean, sterile look, and the KSD attachments in a separate bag. I can't believe I bought this thing. I don't even have anyone to hold the keys. What the hell, I can find someone, and in the meantime get a right fit. Reading the instructions, I was completely confused. What the hell goes where? Well, I have to start with the ball ring, anyway. From smallest to largest, I realized how much larger my balls really are than the average male. Only the largest ring fits, and even then, a bit tight! (Thank god they're not any bigger!) I got it on, and watching a video instruction on xtube, got all pieces in place, with only a few moments of excruciating pinching (too bad I'm not into pain). Now to try a pull out... and yes, I can pull right out. But, fortunately, I can't get back in afterwards! A few days later, I got myself into the CB in the shower -- a nice perfect fit with the KSD inside too. I'm glad to say, I can't pull out with the KSD in. Trying to do so is painful and difficult, and I certainly won't be able to get back in if I succeed. However, as was the case before, I had some REALLY bad pinching using the KSD, but after some trial and error, found an appropriate way to fit everything on painlessly. All in all a success!
