loose? sex?

hi everyone! I’m just here to ask some questions since ima little worried. so about 2 days ago me and my boyfriend had a lot of sex we usually don’t do it this much and afterwards it actually hurt quite a bit, last night I still felt a little sore down there and I noticed I felt looser when I inserted a finger. I’m a really tight petite person in general so I’m wondering if I’ll tighten back up and my body’s just tired and sore atm from all the sex? I’m not sure 100% sure so any comments would be highly appreciated thankyou all so much💖
