I find that when I do anal, I enjoy the physical feeling of being stretched and the mental feeling of having something big in me the most. This means that I'll probably be constantly challenging my max size, so I have some questions about sizing up and safety just to make sure I don't do something stupid. I have no set size goal, so I'll probably just keep sizing up until I become too old to do it safely, or until I hit the hard limits (pelvis for girth, end of the cecum for soft-toy length, diaphragm for firm-toy length). Or until I hit a point where it's not safe for me personally to go farther. Does having a softer material allow you to take bigger toys than otherwise? Since not only would they be more friendly to the bends, they would be able to compress themselves so my bowels don't get strained as much, and if I hit the above hard girth limit of my pelvis, it should be able to safely compress itself through to allow for a higher theoretical girth limit. Would this compression, getting a toy deeper than it otherwise would with its girth, be a safety risk? Would the benchmark for the pressure being too much to handle be too low for it to be practical? How would I go about stretching deep parts of my colon? I've seen people... a person... varka hilt an XL Chance Flared, and with the length of that thing the head's definitely in at least the transverse, if not the descending. It's easily the girthiest toy that can get that deep, so how was he able to stretch-train himself for that? Especially since most depth-training toys like the Slink, even the XL one, aren't even close to that girth at that depth. I've heard that the deeper in the colon you get, the wider its Inside Diameter gets, but at the expense of getting less stretchy. Is this true, and if so, how does it change your approach to toying yourself? Is it perfectly inversely proportional, allowing for the same "max stretch" the whole way? If not (which I'm 90% sure is the case) how much does it limit girth? Recently, when I've been using my M/M Egg Plug (my current max girth), when I'm at the widest point and just about to sit on it fully, I feel this "burning" sensation in what I'm 80% sure is my internal anal sphincter. It fades away quickly when I switch to less girth, by either fully sitting on it or by taking it out a little. Is this due to not using enough / too-thin lube, my sphincter straining against its current max limit, or something else? Is it a red flag, something to just be wary of, or something I can ignore and bust through (probably not this answer lol). Last question, similar to the last: when I've been using my M/M Chance Unflared (my current max length), when I feel myself "slip" into my sigmoid, it gets pretty sore pretty fast. I wouldn't personally describe it as painful, but it's enough to make me stop, and a very small feeling of wanting to remove it. The longer I keep it there, the weaker the feeling gets, and after a while I can take it somewhat deep in my sigmoid with only slight discomfort. Is this just my sigmoid being distressed about taking an M Chance Unflared head without warmup, and can handle it safely? (I should mention that this is the only toy I've ever gotten into my sigmoid.) Or is it a red flag that I should be responding to?
