Are you Breast feeding? That can make you dry which can cause pain. Try some lube if that is the case. Could it also be that you were just tense from nerves? Maybe just relax with a glass of wine next time and start with lots of foreplay. If neither was the case for you I wouldn't call it normal. We DTD after 11 days. I didn't have any pain. It could be somthing simple and may need a Dr assistance. HTH
I agree with Amanda. Dryness can make it painful. If that's not an issue, it might've just hurt because it was the first time. If it continues though you might want to check with your OB to be safe. We DTD 3 weeks PP and it didn't hurt at all.
sorry to ask, but did you rip or have an episiotomy during birth?? if you did, your scar might be what is causing the pain. i ripped a lot(!) and the scar is very sensitive, but it does get better.
