Transmission of HIV/STD
through oral sex
with a female is rare.
Anyhow if you are immuno-competant oral thrush
is not common. But any type of bacterial infection of tonsils and pharynx can occur. It may either be a non STD or an organism due to STD.
Consult your ENT surgeon. He/she will take a swab from your throat and send it for culture and sensitivity for both STD and non-STD organism. According to the outcome of the result appropriate antibiotics selected and it will cure you completely.
