I only had a slight tear, and we had to use lube and go slowly for quite awhile. I can't remember if it was a whole year, but it was at least 8 months or so. And then we were using condoms, which have a lubrication to them. Of course, I also remember laughing at the 'no sex for 2 weeks rule.' 2 weeks - try 2 months! It took quite awhile for me to feel at all ready to even attempt sex.
My SIL had a horrible tear - basically the baby came flying out and actually came out of the pernieum, not her vaginal opening. Her dd is almost 1.5yp, and a few months ago she mentioned that it was still uncomfortable.
