Burning after sex

Lately I’ve noticed that my vagina burns, like - pretty badly, after sex.. and I also have the feeling that I need to pee for quite a while even after I’ve peed (ONLY after sex). I have no other symptoms of a UTI, yeast infection, or STI. I feel like I’m naturally lubricated enough but I did mention to my partner that maybe we should start using lube. I don’t know if it’s friction related or? We have fairly rough sex but it hasn’t been an issue until recently.

Any ideas? Also any remedies to make the burning go away? It sucks 😭😭
