Hey all, we're new here, so hello We recently discovered that we both were quite turned on about the idea of chastity and keyholding and some other, to this post irrelevant, D/s-play, so naturally a Curve was bought and a key handed over as a surprise (on Thursday the 4. so still pretty new to this). Here are a million questions, in advance I apologize for the length of this post, but it is very hard finding answers/thorough instructions, this apparently being a niche product, so if reading a ton of words from someone very new in the game annoys you, please skip this post Now, at the store I went through many debates over which to get, a CB6000 or a Curve, the CB's seemed too small though looked a lot sexier, The Curve rather big and clunky. The lady there thought that I should get the CB6000. I went with the Curve, spending a few hours toying with how to set it up with spacers, what works and what not, now I'm thinking she may have been right. She didn't see my cock of course, so she was probably giving me advice based on her experiences with CB's, but I am over the average size wise, though not in any way gigantic. Currently the Curve is set up like this: Third largest ring, longest locking pin with spacers. Flaccid I almost completely fill the Curve, so I'm thinking that it is the right one, but I'm still in doubt because: (Should be said, being Danish I'm uncircumsized, add to that, I have quite a lot of foreskin, enough to cover the head almost completely when fully erect. Having it removed is not a risk we're willing to take, so actually getting the Curve on is a bit tricky, it's either "excess" skin bunched up at the beginning of the curve or skin stretched throughout the curve and bunched up at the end of it (using a sock to pull everything in there as per advice on this very forum), not that this bunching up matters much, but I'm thinking that this may be why we're having the following problems) When I get hard the curve is pushed forwards, away from the root of the penis, leaving a gap from root to ring while "tightening" up the ball sack. When I get soft again I'm able to more or less pull the Curve back to it's original position by pulling the skin of the balls away from my body while drawing the Curve towards my body, though it is not completely in place at the root in that nice tight way. This annoys me because it sort of ruins the "look" of the device and seems not to correspond with the pictures I've seen of other CB's from the same manufacturer, though I've seen no "hard pictures", so this question may be totally irrelevant if this is normal and intended behavior of the Curve. Can this be avoided somehow, is this because of wrong ring size or because my penis is too small for the curve? Regarding the rings: I've tried all the rings, the smallest one acts like a cock ring, making it impossible to get the Curve-part on the penis and blueing of the balls ensue rather swiftly. Similar problem with the second smallest. The third smallest (third largest?), which is currently in use, has somewhat the same problem when my penis gets hard and while fitting the device, but in no way to the same degree (erections take a while to go down and this represents a very big problem while sleeping, it seems I often wake in pain, and not the nice kind of pain, getting up it seems my penis doesn't care too much and goes flaccid quickly, but still, a full nights sleep is nice). This ring is the best one when penis is flaccid (never written flaccid so many times in quick succession), and to some degree when hard too, except for the nightly pain The second largest (hope my limited grasp of size-description terminology isn't failing too much and muddying the waters of communication and understanding) is very comfortable, but I find it's just too loose when the penis is soft, "crawling" down the shaft and resting on the ball sack, I can fit my little finger through the space that's left and I fear escape is possible, which I won't attempt in an effort to "cheat", but being secure in chastity, knowing that there is no way other than sabotage makes it all the more fun. The biggest ring I haven't tried yet. Am I using the right sized rings? Is there a way to be sure? What are the spacers supposed to do and how should they be used properly, should a smaller locking pin be used? I've used all three, the medium length one in connection with two points of intrigue, the short length alone - same goes for long (both used with spacers). Is it just a question of trial and error? The thing is, she is going away for the weekend, and we'd rather that the device was properly setup and inescapable but at the same time we'd like to avoid slow castration. We do have an extra key hidden somewhere unbeknownst to the male, so if problems arise, he'd be able to get it off/back on. This is just a temporary safety precaution which we hope to eliminate soon. Well, if you've read on this far I thank you, if you have answers we'll celebrate you and you will make us happy! I shall add some pictures soon, so you can see what's what. Lots of love Edit: General tips are very welcome!!!
