I'll do a nice positive one!
I had no pain on crowning, no pain on pushing. Nothing.
DD2 (DD1 was forceps so can't comment on that one) was b2b and contractions felt like being kicked in the back by a horse. But as I got towards the end - and I assume she finally got in a good position - the pain just faded away.
Pushing didn't feel like anything else. It just felt like something was moving down inside me (and, disconcertingly, bouncing back at the end of every involuntary push). My body pushed, I didn't knowingly do so. I just realised after a little bit that it was happening IYSWIM.
I didn't feel crowning at all. No pain, no nothing. I had a second degree tear that needed stitches too. No feeling of 'splitting in two' or anything like that. It was bloody amazing being told that they could see my baby and she/he had loads of dark hair.
Afterwards, I was on the high to end all highs. I felt I could run a marathon and wrestle a bear. Though it's probably a good job I didn't, as I went a bit wobbly when I tried to walk upstairs to bed (was a home birth).
I was in the pool too, if that's relevant.
