I've moved this over to Sex & Pubery.
Were his hands clean when he fingered you? If it hurts to pee and it's a burning sensation then you may want to visit a doctor and get tested to see if you got a urinary tract infection. It happened to me before and it was very uncomfortable but the antibiotics they give you for it helps pretty quickly.
Another reason you are still in pain is he could have scratched the walls of your vagina. Had he clipped his nails recently?
In the future, be sure to go slow and use lube if needed. I'm glad that you had him stop as soon as it got painful.
