Gninori put it quite well, but nevertheless let me try to explain something... In electrical engineering we have a concept of signal-to-noise ratio (SNR). It represents the ratio of a signal (meaningful information) power to the noise power corrupting the signal. I personally like the idea of extending it's meaning to biological system functioning as well, which is not uncommon. Our organism performs millions and billions operations per day, or even an hour, and they are all influenced by the noise generated from external influences (microorganism, radiation, toxic substances and gases, etc) and internal toxic by products. Fortunately, much like a well designed computer system, our organism have redundancies, error checking and correction algorithms, ability to compensate for deficiencies and even self repare. Not a single cell or one of its functions is controlled by a single mechanism, in order to avoid catastrophic failures in case something goes wrong. But what if something goes wrong in several places at once... disturbing or completely destroying multiple of a function corelated control mechanisms? That's why we can regard an illness or a disease as a complex entropy disorder which occurs when the SNR for a particular function is degraded beyond signal resolving level. The thing is, (for now) no one can measure your system's SNR, nor SNR for a particular signal/function in your organism, so we don't know how wide is someone's "dynamic range" for a particular organ or a function. Most of our properties we get through the genetic material, but some of it we also acquire through life by exposure to the external influences. What I'm trying to say is that no one can tell you for sure whether you'll get a lung cancer if you smoke, or would you develop a serious rectal prolapse if you frequently strain or stretch your anal area, but you are certainly degrading your SNR for a particular function, putting your organism to an increased stress. And you can assume that you have much greater chances for tire explosion if you drive 100mph, then if you're driving 40mph. And now... back to your questions.

If one of the behavioral causes for prolapse is "straining", it seems like this entire community is at risk, because abdominal downward pressure is a common feature of assplay, at least in my experience (For now we can leave the issue of what effects putting large things in the ass). You can see from various vid clips how different people play, for example, Kirk has arguably the largest capacity of anyone on the scene, but I can't recall ever seeing him push his ass out (straining downward pressure) during play. Same for Chris (Freton and Chris), she has achieved a great deal of flexibility and volume, and I have seen her push out a bit, it doesn't seem to be a feature of her play. On the opposite side is someone like Mila, who seems to like pushing out really hard. Can you gives us some good, mildly technical descriptions for laypeople of what is a gape, a rosebutt, and a prolapse, ? Firstly, lets define those terms... I would define a 'rosebutt' as a racily swollen and prolapsed hemorroidal plexus accompanied by mucosal prolapse or a small full-thickness rectal prolapse. 90% of all Internet famous 'rosebutts' are probably caused by prolapsed hemorrhoids and rectal mucosa. I can't claim that any rosebutt will progress to a full-blown rectal prolapse, but then again if you have one (rb) then you either have a predisposition to rectal/mucosal prolapse or you were that die-hard in your training. Either way you have good chances to develop a symptomatic medical condition if you continue your practice... especially when you consider ageing process which deteriorates connective and muscle tissue functions. Remember SNR? A 'gape', on the other hand, is not a medical condition and could merely represent a relaxed/dilated state of an anal sphincter. Large gapes however are possible only in "highly trained" butts, in which connective collagen fibers and subcutaneous part of external anal sphincter are overstretched. It is also possible that big 'gapers' also deteriorated their anal cushions and fatty masses in ischiorectal fossa, which allows for such a large expansion of anal canal. On the other hand, we always have to consider inbred anatomical variations, so some people are probably more 'talented' in this then the others. Regarding rectal prolapse and it's etiology, I don't think that it has anything to do with excessive straining it self. It of course could be a contributing factor, but not a primary cause of it... and recent researches are supporting that theory. Mechanical trauma to a rectum is something I would worry about though. You don't have to be predisposed to anything to get your leg broken, or finger nicked, so same stands for mechanical trauma to the rectum. That's why I would avoid deep and vigorous thrusting with any object, no matter how good it might feel. QUOTE(sinkhole @ Jul 17 2008, 07:44 PM) [snapback]102170[/snapback] So back to Kream, her ass looks like it pushes out with contraction like force when she cums, but otherwise (before warmup) her ass doesn't just hang out, or like she has no control over it. Rectal prolapses mainly manifest during defecation (straining). And I hate spoiling your fantasy, but I don't believe that Kream ever experienced an orgasm in front of the camera. Those 'fountains' were just simple urination for theatrical purposes. Whether Kream has any difficulties emptying her bowels is beyond me, but she will probably require medical attention sooner or later (ageing process is remorseless) - especially if she delivers vaginally. QUOTE(sinkhole @ Jul 17 2008, 07:44 PM) [snapback]102170[/snapback] Per my last post, would you say anyone with "circumferential internal intussusception" is headed unconditionally for surgery? I.E., if you have a rosebutt or gape now, it's gonna need to be trimmed later? I know it's kind of an absurd question, but can you say "generally" what the point of no return is in terms "training", i.e. if you stretch past a certain point, and what anatomically exactly is getting "stretched"? If the pubo-rectal sling get's stretched, would that allow for intussusception without turning into a sliding hernia? First of all, I don't believe rectal prolapse has anything to do with intussusception, which is completely different medical condition. It might theoretically look like one, but it's not. As I've explained it earlier, it all depends on your anatomical properties and your's 'system SNR' - namely your organism's ability to compensate for stress/noise that you've introducing. Thus, it's almost impossible to determine what's generally safe, without staying miles below limits that most of stretchers are pursuing. In order to avoid any muscle damage, it is considered scientifically safe to stretch anal sphincter up to 130% of it's optimal length, which translates to 13cm in circumference, or 1.63" in diameter. That is obviously far under expectations of many stretchers. What amount of stretching would damage enough muscle fibers in order to produce incontinence or other medical condition symptoms is very dependant, but I can assure you that any self respecting stretcher here would have necrosis and fibrosis in histological finding of his anal sphincter muscle. Considering that ageing will inevitably further deteriorate anal sphincter... you could imagine that any stretcher lowers his/her SNR in that region and increases chances of becoming symptomatic some day. What you will make of all this is your thing...
