When I Have A Bowel Movement It Just Hangs There,

when I have a bowel movement it just hangs there, It's not very big around. I have to pull it out with my hand and push at the same time but there is a stretchy feel to it like elastic with some stool formed on it. This has been going on for over a year. I can't get my doctor to send it to the lab and she doesn't know what is going on. Please help!!! I do take metamucil daily.
