My girlfriend says every time we have sex her vagina hurts for at least a day. It doesn't matter if it's sex for 5 minutes or an hour. She said peeing hurts really bad too. We're both clean and have only been with each other for years. She said it wasn't a problem when we first got together (or was a different kind of sore... I'm not sure what to make of that.) However, after about the 6 month mark, she said it became painful after sex. She also said it was never an issue with any previous boyfriends. I always try to make sure she's well lubricated before penetration. She's said that using lubes can actually make it burn more. I never have to push hard to insert and I always try to be gentle. Is there anything that can be done to prevent/ease her pain?
