Rough sex and damaged vagina?

Sherry
So I guess my boyfriend was going pretty hard while at it and damaged my vagina because I just went to the bathroom (it's been a couple days since then but I just noticed) and saw I have a sort of cut looking like in my vagina opening. It looks red or as if it was dry blood, I'm not sure. But i tried touching it and it hurts a bit, kind of like a burning sensation. I don't feel it unless I touch it but I'm scared because I don't know what it could be. I'm not sure if it was because how hard he was going or how it would take us a while to get it in while he was dry so we'd force it (since I'm on birth control and we don't use condoms). Any help or opinions would be great And sorry for the details 😅
