You have no medical training so you should have zero faith in your ideas about hiv infection. Instead, you keep telling us we don't know hiv risks but only you knows how hiv is spread.
It is time to see a therapist instead of wasting 3 more months afraid of your own incorrect ideas. It's quite silly of you to make up hiv ideas then believe them.
