I got fingered and my boyfriend used two fingers for the first time. I felt okay after we finished. When I went home, I had to pee and it stung. The next day it started getting really itchy down there that I couldn't help but scratch it. This morning, I checked what was wrong with my vagina and I found out that one of my labia is swelling really bad and has blotches. I'm also on my period and whenever the pad lightly scratches it, it hurts. What is this?
