I had tears up into the vaginal wall, on both sides, and I was perfectly comfortable having sex after about 3 months. To be fair, we would have tried earlier, I was up for it at about 6 weeks, but my bleeding didn't turn to spotting until 3 months, and that put us both off for a while. Interestingly, on one side the vaginal wall tear continues externally into my labia minora, and the repair work didn't quite take - I now have a 1/2cm diameter hole in the labia. Just in case I ever want jewellery there.
