I have noticed that I cannot pass wind silently any more whilst standing. It makes this weird slapping sound no matter how little gas pressure there is.
My CRS said my sphincter is not tight since he easily put his finger and camera in.
But I do feel tight there, I have that golfball in the rectum feeling like I constantly want to push something out.
Can your sphincter be tight even if you can put two fingers in?

I think so reckless :( it might be that while the wind is passing - the muscle constricts thus making the sounds :( Hang in there sweetie.. and follow the eating/drinking/softener lifestyle..
