I also enjoyed my labour experience and am really excited to do it again. Like sasha said - you get the most amazing feeling of accomplishment and feel like you can take on the world.

yes, it hurts and I'm not really very tough when it comes to pain but labour pain (usually) builds up gradually so you have time to adjust and I really focused on having a positive perception of the pain. Plus, once the baby is born, it's all over (although you are still pretty sore for a while).

There's nothing wrong with using pain relief if you want to - I know people who swear by epidurals - I think they make the whole experience a little more... civilised?... so it all depends on what kind of experience you want.
