I was intimate with someone who is HIV positive. This person is on antiviral meds (they showed me the bottle), and aside from two attempts at oral s** (where he did not ejaculate but there was likely per-seminal fluid) I did not do anything that carried a transmission risk. But… it only takes one exposure, and it only takes finding out this person’s viral load was above threshold levels, and I am royally screwed. On the one hand I want to run to the health clinic and get on PEP (post-exposure prophylaxis). On the other hand statistically my chances of having been infected are virtually non-existent. This has scared me off of s**, possibly for good. I had always worried about STDs, and I am usually such a cautious person. I feel stupid and dirty.
