However, I did kiss her for an extended period of time, with some
tongue involved. Normally, I know this exposure carries no risk of HIV. However, I have dry mouth syndrome, which means my mouth produces less saliva, and my tongue tends to be dry all the time. Saliva protects against HIV, so the question is, am I at risk of HIV from this exposure because of my dry mouth? Does my dry tongue, increase the likelihood of blood from her mouth penetrating my bloodstream?
