I have a red sore that bled for a little while after receiving oral sex. I have been with the same person for a while and got checked the week before just for a regular check up. It was the first time using lubrication and ever since then the discharge has become thicker and the clitoris has been very sore and sensitive to the touch what could this be? could i be allergic to lubrication i used KY and also it wasn't the first time receiving that from my boyfriend.
