HPV is not common enough in the mouth to be passed by kissing. Yes you can get HPV from oral sex but it is rare.
Please forgive my further questions. I am not trying to be inconsiderate; however, I am confused.
I am by no means an expert, but the reason for my question involves recent research on the subject.
I have read that performing oral sex on someone with HPV can lead to an oral infection and that HPV DNA is found in 70%+ of oral cancer biopsies.
With that said, I don't understand what is meant by "does not affect the mouth".
No because HPV really does not affect the mouth.
