What a fantastic story! i'm really really happy that it was a more postive experience than last time. I can't believe you were dancing!! haha. I'll have to try that next time.
When I had Ben it happened so fast (3 hours) i didnt have time to have any pain relief. Afterwards I was so proud of myself - as you put it - it felt like it was something that i was doing, rather than something that was happening to me. It felt so natural and i could actually feel him coming out. So it sounds very similar to your experience :-)
Congratulations once more. You should be really proud of yourself.
