Had one with my first, but not with my second (it was too late for one by the time I asked about it).
The one I had with my first was fabulous. It actually speeded things up, because my body relaxed, things had been progressing pretty slowly up untill that point.
I pushed the baby out- even though I could'nt really tell whether or not I was pushing- none the less, out she came, no stitches and I aws up and about shortly afterwards - I needed to use the loo! I also had a shower soon afterwards- they had one of those stool things that old people use in the shower.
I was fine. No ill effects afterwards for me or the baby.
I went through the second au naturelle (that might actually be real french there) it was ok- well, no, it wasn't really, but it ends so quick (whn the baby is delivered) that you kinda forget it was happening if you know what I mean- there's no pain wind-down just wham, pain gone.(no stitches tho again)
i think the trick about avioding the stitches is not to push the baby's head out too fast, if you can help it, there is a crazy buning sensation when the head is about to be delivered that makes you want to get the baby out immediately, it doesn't hurt exactly, it's just real odd.
I didn't feel any really strong contractions, so I just stayed at that point for, probably just a few moments- the top of the baby's head was already visable, and I just let her sit there for a moment, and then gave one more push when I felt ready. My skin and whatever had a chance to stretch itself, before I delivered my babies head, so it didn't tear. The first time I gave birth I had the epidural, which made it harder to push, so her head was delivered slowly too.
You'll know the feeling when it happens- it was good to have a go at a natural birth thuogh, I must admit that- well, no, it was caca, but I know if I ever have another baby, and i'm, like, stuck in a cave or whatever when I go into labour- I know pretty much what's I n store, and that i've done managed to do it once before.
I don't know which way i'll go next time though, if i'm not in a cave that is.
