I am 23yo female and my SO and I just had sex (kinda rough ) I felt my vagina afterwards and noticed a big bulge on one side of my ureathral opening. I looked in a mirror just to make sure it wasn't my labias, it was definetly ureathral opening. I'm super freaked out bc it looks like a blister almost. Do I go to a doctor or ice it bc of the swelling? I went pee and it didn't burn and it doesn't hurt to touch it. Wtf do I do :( help please.
