My girlfriend hiv tested (-) after 6mth window, gave her oral sex now I have lesions on my tounge with cough and I have no clue what it could be. Help?

Not HIV on tongue. I'm uncertain what this rash is. I would ask her to see her physician to make sure she has no female infections. You can also see a dermatologist to look at the rash on your tongue. I will discuss this with your physician to consider your options.
