After having oral sex (just oral for a short time )with a tran sexual three days ago, I sensed that my lips get dry ,one they after i got a mild burning (like mild chilli) in my mouth, mainly noticeable on my top of tongue, gradually my lips and top of the tongue get better but the middle of tongue and my throat start mildly burning .it seems that it go forward little by little ! I keep examining my tongue and can see it became more white but there is no strange or specific white mark , could you please give me an advice? could it be related to any STD disease such as HIV or ...?
Your knowledge will be greatly appreciated.
Many thanks
