I have tried for a few years now going deep passing through into the sigmoid colon but have had no luck & really are desperate for some advice. I have tried flexible dongs for a warm up 1.5" & 2.2" in diameter but no luck, also tried every lube & position & being relaxed as I can. I have found waterbased & J-lube are the best.
Trying to take a reasonably wide object to build up for a fist.
Here is my problem in short as best as I can tell.
I can usually always take a 2" wide dong into the sigmoid straight away before any cleaning waste out of the insides. As messy as it is sometimes the dong goes in easy with what ever lube is there & the pipework feels straighter. I can usually enter the sigmoid if there is an urge & a decent amount of waste is naturally expelled into rectum.
However once most waste is gone & after I flush my insides & all is clean with no waste it is very sensitive at getting into the sigmoid even if using alot of lube & going slow, the sensation feels a bit like tension like muscles being stretched. It also feels highly curved like a spiral staircase but I'm not sure. It's simply too sensitive bordering on painful to go any deeper beyond the slight entry mainly for fear of damage. Maybe the entry area becomes highly sensitive after a while?
I don't understand what is preventing me going deeper & why so much sensations? I use so much lube sometimes (few 100ml in syringe) & it makes no difference. I can tell J-lube is better over standard waterbased though.
Strangely I have found wider flater objects go in with less stressful sensations vs the standard penis tip of the dong". The smaller diameter objects feel like there poking while the larger feel like there opening. As an example of how strange this is for me. Imagine a Basix 12" dong with no balls just the wide suction base. I can actually take that end into the sigmoid easier than the smooth cock end, alot slower of course but not as much strong sensations. However sometimes small reddish lube colour appears.
I would love to be able to get a camera up there to really see how it is after & before a clean out. Are there any cheap camera setups that work? I tried a endoscope usb camera but it literally was a blur.
Please help with advice on going easy into the sigmoid thanks.
