You can't get HIV from a tissue. All your previous posts stated the risks. Unprotected vaginal or anal sex or sharing IV drug needles to inject drugs. I say with care, you may want to discuss your anxiety with a professional to receive some coping skills so this doesn't keep bothering you. But, no risk.
Reread about only. Consider therapy for your hiv fixation which is a bit of a mental illness at this point since you have been told the only risks 3 times now (within 2 months.)
It is time to move on instead of continuing to ask questions that are irrelevant - however it seems you can't move on so see a therapist.

Reread about the only ways to get hiv since the word "only" presents a roadblock to your questions. .

Besides if hiv lives for 25 days then we would all have it by now.
