I'm In A Long Distance Relationship And My Girlfriend Came

I'm in a long distance relationship and my girlfriend came for a visit last week and we had sex. We used a condom but it broke and we continued on. A few days later I soreness and noticed a small cut or sore on my penis that I thought was due to rough sex on my behalf and her being kinda of dry....a week later I'm still sore at the tip of my penis and it also looks like the pee hole has a dark ring
