sex injuries???πŸ˜‚

So I've been VERY sexually active with my boyfriend in the past couple days and I think I may have gotten sorta of like rug burn down there from it and it's sooooo painful when I pee and even when I'm not it's uncomfortable 😣 . Has this happened to anyone else? How much do you guys think it will take to heal ? And what should I do to help it heal ?
