Three days ago me and my boyfriend of 5 years had sex. I wasn't sore that day but the day after my labia were slightly swollen and sore. This has happened before after particularly rough sex but occurred straight away and went down within a couple of hours. It is now a lot worse and is painful inside the vagina and I keep getting an itching sensation inside too, but there is no rash or external itching. Me and my boyfriend have never been with anyone else. Could it be connected to the sex, which wasn't especially rough, or could it be some sort of infection?
Thank you!
