He went to long and too rough

So I've been with my SO for almost 3 years 
You know in the beginning its TONS of sex, long lasting nasty sweaty rough sex. For the last 6 months or so our sex has gotten more gentle and slower and it doesn't last as long. We finish and then we cuddle and fall asleep. I don't know what has gotten into him and I'm not exactly complaining but my vagina hurts. We didn't have lube so he spent extra time with the forplay and he was like nasty HORNY like I haven't seen him like this in a while, he lasted so freaking long and was so rough with me. I came about 20 damn times I swear and I was wet the entire time so I don't understand why my vagina feels like it's raw as hell. It burns to pee now and it's like throbbing. Like damn you could have told me I would have spent the whole day preparing myself to get my brains fucked out. Now I have a bursting headache too 😭😂 like thumbs up dude but damn. 
How long will my vagina hurt like this? I don't remember it ever hurting like this in the begining.
