Hello, me and my boyfriend had sex two nights ago and it was pretty rough sex, we were both very wet and used lubricant and when I was on top he had slipped out and his penis hit my vagina and it hurt extremely bad. I figured it was just a bump and it would go away but after sex I noticed my right labia was swollen twice the normal size it should be, I figured the next day it would go away. The next day the whole right side of my vagina (just the outside) has turned purple and looks like a giant bruise! Is this possible? Is there anything I should do?
