Idk what this is

So I had some pretty rough sex today. And after, I used the restroom and it burned. And I’m pretty sore tbh. Rough sex is what I like. But with partners they’ve never delivered like this. And it was pleasant.

Well I get home and ya know I’m sore and whatever. And I take a shower and look at my vagina. It hurts.

And normally after sex I get swollen and it kinda hurts and idk why

Well I just got home from work and like i take a look again and I notice something, so it kinda looks like dry skin. Or like raw skin ya know? And it has a kind of yellowish look to it. And idk what it is.
