My doctor gave me a suppository for hemorrhoids yesterday, but every time I try to shove it up my butt I get this sudden, uncontrollable urge to poop and it just comes out everywhere. It's like when you stick your finger down your throat to induce vomiting. I've tried not eating anything for a few hours, but I just keep pooping every time I try to insert the pill.

The pill is pretty big, so I have to spread my butt cheeks apart with my hands while I have my wife shove it up there. Is it possible that spreading my cheeks is the cause for all the pooping? Should I just try to hold the pill in place and then sit on it really hard? Perhaps I should shove it up there real fast and then shut my butt while I try to suck the poop back down? Please help, I've already ruined the sheets on my bed and pair of my work shoes.
