Did you have an exposure?
Recently I had PROTECTED sex with a female acquaintance who is HIV-positive. I shaved a couple days prior to and had a very small cut in my pubic area.
HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.
You never had an exposure.
You seem very knowledgeable on the subject and I thank you for your help.
