TMI! Pain

Last night me and bf were going at it. First time he went in felt a little dry so it was obviously uncomfortable felt a bit of discomfort so we stopped. Few a hours later we did again , but this time it was no pain at all. Fast forward this morning I feel that same pain again almost like it’s right in the entrance? What do you girls think … maybe he burned me w his skin or could it be something more serious lmk
