So a couple of days ago me and my boyfriend had really rough sex . And he has long nails and he fingered me and it hurt a little bit after a while like the inside of my vagina started to hurt a lot . And till today it hurt to much when we had sex . Any clue on what could have happen ???!! Could it be a cut ? I tried to open my lips and take a video on my phone to see if there was anything there but it was all red and couldn’t see nothing . But it hurt so much to open .
