After having sex today I noticed that only one side of my libia major is super swollen (almost three times as big as the other side, has baby cuts along it, is super dry, hard, and burning. Earlier today before having sex I shaved then noticed that my outer libia was itchy and irritated. I didn't really think anything of it because it usually happens after shaving. Then after sex I noticed how swollen it was, and how it hung a lot further past the other side. What could be the cause of this?! Should I put 1% hydrocortisone on it? Help!
