TMI guys seriously my vaginas really swollen

So earlier I had some pretty long rough sex now both side of like the inside of my vag lips are so swollen I've never seen anything like it. I've had the same thing happen a couple times and it hurts to walk my vag rubs on my legs. I know it'll go away eventually but does anyone know what causes it? No condoms involved so it's not that. And also does anyone know if any tricks to make it go away faster? Thank u
