I had 2 land-births. DS1 I had the ring and a slight tear. DS2 was suppsoed to be a water birth, but he came way too fast - only about 45 min of labor. No ring, in fact a completely painless crowning and I was totally intact. (The labor and transition was hell though!)
The difference - with #1 I had no urge to push, so I was just bearing down with all my might and trying to get it over with. With #2, even though he came so fast it was very steady. As soon as I was out of transition I had a strong urge to push, but it was a very natural and slow push. I supported myself as well and felt his head bulging. The second push was effortless, I just let my body do it, and his head slowly emerged into my hands. I was terrified the first 30 minutes, because I thought I was in bad endless back labor, but as soon as I was out of transition I was so blissed out and calm, so I'm sure that was a factor. I was not clenched in any way.
DH and I had DTD right before bedtime (DS2 was born appx 3am) and I had a very good time, so perhaps that also helped with my overall relaxation.
