You seem very knowledgeable on the subject and I thank you for your help.
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.
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.
Did you have an exposure?
