Given the data you provided (oral intercourse with HIV positive woman, penis discharge, sores on the inside of the lips, white, hairy tongue resembling thrush, negative tests for Chlamydia, Syphilis, and Gonorrhea, negative tests for HIV (both antibodies and PCR RNA), you might be experiencing a fungal tongue infection.


HIV infection is highly unlikely given the results of the tests you reported. The results of the HIV antibody tests might be negative after three months if the person had previously taken antiviral medications. However, the negative PCR RNA is very accurate and it is highly unlikely that the viral load is undetectable after 3 months of possible infection. The fungal infection might be accompanied with either bacterial or viral infection of the mouth mucosa.


It is unlikely that these infections are caused by decreased immunity due to HIV infection, which in most cases takes 10-15 years after exposure to occur.


You might want to talk to a specialist for infective diseases about your results and whether you need an additional examination.
