I think what you have is called Bartholin Cyst. Ask you doctor about it. Good luck!
I am having a bit of the same problem. My clitoris is very sore and peeling a little. I also have a red bump outside of my vagina which is sore. My bf and I have been having alot of sex and foreplay which I believe has led to this. As of yesterday, we decided to take a break to let me heal. How long has this been going on for you?
