Hey there,
I am a 32-year-old male. I have chronic hepatitis b and I have been taking Viread (Tenofovir) for about 6 years now. My viral load is undetectable and has been for years.
Is there any risk for a person who wants to perform oral sex on me without a condom if that person is not vaccinated?
How contiguous can my precum be considering that I am undetectable?
