I had a cut on my lip and the morning after giving my girlfriend oral sex I had small bumps on my lips. They looked like small pimples but on the corners of my lips. They have turned into sores and its been about 10 days and they are dried and haven't healed. Wanted to see what it might be. This is not the first time I have given her oral we have been together for about 2 years and have been sexually active for a little over a year. This is the first time this has happened to my lips. It has happened to my fingers before and after my finger healed it would only come back if it came in contact with her vagina. Neither of us has been with anyone else.
