Please help.!

Okay so my bf and I had sex yesterday and it was for a very long time and it was really hard to push his ... You know inside so he have me oral. And after we finished I noticed my vagina was swollen... And last night it was huge I opened my legs as far open as I could and my vagina lips were still shut. It's still swollen now and last night I woke up at like 2am it itched and burned. Now it's still burns and I just went pee and it hurts to wipe I google some stuff and a lot of girls had discharge so I checked by slow sticking my pinky up there Bc it's the only one that will kinda fit and when I pulled it out there was chunks of white and a milky liquid.... What's wrong with my vagina.??!
