Also, from what I've read on there, it seems like some people scream whereas other people are pretty quiet/calm, it all depends on the person and the labour. Most women tear, but more often than not they seem to either not notice at the time or not care because they have a new baby very shortly after. Whether or not you get stitches depends on the size of the tear (and probably also on where you give birth - if you do it at home, you're probably not getting stitches for obvious reasons). As for the post-birth vagina thing, I have no idea, they never seem to mention it!
