My vagina is on fire 🔥

Ladiesssss! I need your help. So yesterday I went over to my boyfriend's house and we had the best sex ever! We hadn't seen each other in two weeks because we were both busy with work and other life commitments, so as you can imagine our sex was over the top.. but now I'm sitting here with a burning vagina. Is it normal to have a painful vagina after having sex for a long period of time?.. and is there something I can do to sooth the pain?.. thanks !
