I had sex for an hour straight this morning and my viginia is swollen and urts when i pe we had no lube wat can i do?

Give it a rest.: No more sex until the pain and swelling reduce.

Physical irritation?: With a full hour of intercourse, this likely is nothing more than physical irritation and minor trauma. You could have a yeast infection, made symptomatic. Possibly latex allergy if a condom was used. Give it a day or two (with no sex). If things don't improve, or if you develop any other symptoms like blisters, sores, or vaginal discharge, see your doctor right away.

Rest: Time heals all wounds. Just give it some rest, and you'll be feeling back to normal in a day or two. Hope this helps!
