Anyone else have gay poopygasms???

I noticed on days where I've had a lot of fiber, that my poop is rock hard and if I hold it in for a few days, I have a big log just chilling in my butt. It feels really good when the big poop log presses up against my prostate so I like to frick myself with it by pushing it out and sucking it back in (over the tub) and I've gotten so good at it that I can c*m hands-free.

Only problem is, that as I'm cumming and having epic poopygasms, my butt convulsions mush up the poop, which totally ruins my fibrous poop dildo. Should I just let the poop fall out of my butt and put it back in for later, or is there a way to not mush the poop or pinch my loaf????

Any tips and tricks would be much appreciated
