Sore after sex

(TMI warning lol) So my boyfriend and I hadn’t had sex in about two weeks because I got a UTI that lasted a few days, then we were at my moms house for 5 days and I got my period, then we were at my dads house for another 5 days for the holidays. We got back and had sex finally. We did it twice that night and again last night, but when we did it last night I was a little sore inside from the night before but nothing hurt per say. Well this morning I woke up and it feels like right around my vagina the skin is very tender and burns when I pee. It’s not a UTI I know the difference, it’s almost like I wasn’t wet enough so the skin around there got rubbed wrong or something. Has this happened to anyone else? Should I be concerned?
