Hello, 2 months ago I licked a guy's penis for one sec, actually I just touched it with my tongue for less than a sec, I don't know if he had precum (what would it taste like?). Also 2 days after that encounter I had a VERY small cut on my lip, but I don't know if i had it before two days. now after 2 months the only symptom I developed is diarrhea.
I still see this guy regular and he claims he never had unprotected sex, but I don't trust him.
So my question is what is my chance of having HIV? Should I go get tested?
