You can NEVER get HIV from Oral sex. NO way. Ok, these are some of the things that makes the transmission from oral ZERO;saliva does contain substances that have anti-HIV properties, Also including that not all mucous membranes are the same. Some, like that in the mouth, are much more durable than the mucous membrane of, say, the urethra. The chance of trauma from the amorous activities involving various "poles in holes" is less in the oral cavity than, say, in the anal canal.
why did I never have a risk I thought oral sex has risks?
Would My kindney disease cause me to have a false negative test?
You never had a risk and your conclusive negative test further proves it.
