Hi docs 66 days after act oral without condom and sex with a condom with a unknown girl i tested negative(ag-ab combo test) 0.444 result. am i good or not? thanks in avance:?

That result is negative and is 100% proof you did not catch HIV. No more tests are needed. (You also had a zero risk exposure. It is the rare "unknown girl" who has HIV; there has never been a proved case of HIV transmitted oral to penis; and condoms are effective prevention during vaginal sex. No worries at all, even if you have future similar sexual experiences.
