I used to do something sort of like what you're talking about when I was younger, like 10 years old...I hope I didn't have my hemmies back then! (I'm 23 now.)I think I had a hard time telling when everything was out. I'd keep pushing and pushing, and mom or a dr or someone said at one point that I was sort of pushing part of my rectum inside-out. When I stopped pushing, it sucked back in. And it was mucus-y. I know because I thought maybe I could just wipe it away and be done with it, and all I got was mostly mucous.. I know, ew.... I think the hemmies feel more like a little bit of poo stuck inside, whereas I think the old stuff was a larger feeling of overall still having to go. But that was a long time ago. I don't think I had IBS then, either.Sometimes I've just got to tell myself that yes it feels like there's something still there, but I just need to stop trying to get it out, and wait for more of an urge. Whether that means sitting on the toilet a while longer, or pulling up my pants and doing something else for a while. Usually I wait a little longer on the pot, then get up...and I eventually forget about the goofy feeling in my bum, if it's just hemmies. If I really do have more waiting to come out, I get the urge to go before too long.
