Ok, basically, I went to take a crap but it wouldn't come out. It felt really big and I just couldn't push it. I then left it for a while, then suddenly it started pushing again. After a bit, my body automatically tensed up without me being able to control it, and it hurt like anything, but it finally came out. However, now it feels a bit weird, but I'm not sure there's something wrong. Has this happend to ne one else, and is it dangerous?
