Went over to this plates house last night. We had sex for 3+ hours straight, I came 4 times. This was my second time hitting it raw and it honestly sucked. I don't know why but when I went inside it hurt, kinda. It felt like she had something in her pussy that cut my dick. It felt like when your dickhead touches stubbles on a just shaven pussy, I can't explain it.

We tried to have sex in the morning but it was impossible, my dick legit hurt like I had a small cut on my dickhead (im circumcised). It looks a bit red.

Should I be concerned? Is this an STD? We had really hard sex though so maybe I fucked her a bit too hard? Anyone else had this?
