Sore itchy vagina

I have been sexually active with one person for 2 years. I was his first, he was mine. Anyway, last night my boyfriend and I have really ruff sex. We have had ruff sex before. This time was different though. I went to bed with a really irritated sore vagina. Yes, I was wet and we used lubricant aswell. His penis was also very sore. Considering we have done this many times before and what not and never experienced this. Anyway. So we woke this morning he was fine. But my vagina, like the inside was itching like crazy. It has been itchy all day long. We decided to try and have sex tonight. I couldn't even take the tip of his penis inside of me without wincing. The pain and itch was unbearable. He put his pinky finger inside of me just to see if it would make a difference and same god danm pain. What could this be. Any ideas, thanks in advance.
