Okay. Thought I'd ask. So here goes..
2 years ago I had a one time encounter at a party with a total stranger. Gave fellatio to completion. Then I started to freak out about the risks of diseases. I had a hiv test at 2 weeks, 6 weeks and 6 months, all came back negative. I guess I still have lingering concerns in the back of my mind. Is there reason/concern enough to take another test? (note: not been with anyone since).
