I pushed for about 1 hour with my first. (never felt the urge to push, actually, and I didn't have an epidural, either. But the good part was that I could stop without difficulty when she was crowning, so I didn't tear.)
About 10 minutes (4-5 pushes) with my second. I couldn't believe she was out already! Also no tearing! Hurray!
Both girls were about 7 hours of labour from first contraction to the end.
