I'm interested in this too...

Someone correct me if I'm wrong, I don't have any experience obviously, but my understanding from what i'd read and heard, was that it is kind of like when you need to do a big poo, and it's going to come out but it kind of hurts, and you feel as though you need to push it out, but you breathe and allow it to make its own way out (lol, yes I know we've all got nice and graphic images of poo now ). Well, somewhere I read said it was a bit like that, though I don't know if it was first hand experience or not.

Sorry if that is a bit graphic, but is that about right? Or not?
