| | Tender bump on outside of my vagina
I noticed about two weeks ago a small number on the outside of my vagina, about 2 days after being with my boyfriend. It wasn't painful so I ignored it, thinking it would just go away. I was laying down in bed today and noticed it was still there, but larger and rubbed my finger across the top. My nail must have caught it and it popped (kind of like a pimple) now there's a small hop there. I noticed it a few days after having oral sex with my boyfriend, and now I'm extremely worried. Any help on what it could be?
