URGENT. Bleeding & pain

I had sex Tuesday the 21st ( 2 days ago) & it was literally amazing sex.

We did it for 5 hrs and towards the end I was obviously extremely sore, like he would touch me and I was in pain.

Yesterday I had some pain and was still swollen down there. I would pee normally but when I would wipe it was like a pinkish very very light color.

Today, I’ve had a lot of urge to pee, like in the past hour. The first few times I was okay. Note: I’m still swollen & sore.

The last 4 times I peed it started to burn a bit and when I wiped there was a little bit of blood.

So I pee and when I’m done I immediately get like an uncomfortable sensation.

What could it be? I think it’s that I’m super irritated From the sex which is causing this.

Please help, this has never happened to me.
