Had an encounter with someone unknown hiv/hep c, briefly made out for 2 seconds, 2 n 6 week tests negative. should i still be worried? i have anxiety?

Low probability: stay calm and do further blood testing in a few months

Saliva X-change low: Risks from what was called making out in my day are quite low for transmission. Perhaps not zero - but close. So, don't worry too much - your test results should reassure you. But even w/out serious health risks, you may want to consider the emotional meaning of getting that close to a person you don't know. I'm not at all prudish, but self worth makes me enjoy being physical w/ folk I like.
