What Causes Pain And Bleeding From Vaginal After An Intercourse?

A day after intercourse, I used the bathroom and as I wiped, it hurt the inside of my vagina and started bleeding. After intercourse I had felt my partner scratch me inside accidentally so that may have caused the bleeding? And now it burns in that spot when I urinate. I decided to look inside and right in the center after going in the vaginal whole, there seems to be what appears skin hanging and that's what's uncomfortable because it hurt when I touched it. I have been tested for stds so I know for sure its not that.
