What's wrong with my vagina lol

haley

So it's Saturday and Tuesday me and my boyfriend had sex as we do most of the time. He got me super wet and turned in then he started to give it to me (doggy style) and it's like I dried up and it started hurting, he ended up finishing and my vagina hurt so bad I cried a little when I got home I started changing to get in the shower and took off my underwear and my labia minora one side was super swollen I didn't know what was doing on and I took a shower and it was gone by the best day but these few days my discharge had been crazy. Anyone know what could be going on?
