I DON'T KNOW WHAT I DID!

Okay so I just had sex for the first time, and it hurt so it didn't last that long as I told him to stop right? But we did not use a condom and now I feel stupid bc stds and that crap, and my anxiety is overloading me right now! It was in the moment and I'm scared and I don't know what to do help me please😣. ( He never came inside me btw.)
