NAY. I haven't had time to read all the responses so I apologize if this is a repeat. But most current research says the cons outweigh the pros of an episiotomy in most cases. One example my OB gave me was to take a whole piece of paper, grab each side and try to pull it apart by pulling your hands away from each other. It doesn't rip. Now put a small tear in the middle of the top and try the same thing. It usually tears easily. Same with you. Also, just because it's easier for the doc to stitch up a straight cut doesn't mean it's better for YOU.
As for personal experience, I had quite a bit of tearing with my first. With the second I had a tiny tear that didn't even need stitches. And with the third and biggest, no tearing at all. In my experience, the actual giving birth part was the same, I literally couldn't tell if there was tearing or not (and even asked my doctor if she was sure there wasn't with the third since he was so big!). The only difference was with the recovery time. Stitches definitely made me feel more sore afterwards but that would be true with an episiotomy too.
Do your kegels, and if you have a chance, I would highly recommend taking a prenatal yoga class. It was soooo helpful for me!
