Hello
I performed oral sex on a stranger (male) who's claimed to be HIV negative (test date unknown) and my dental braces (worn behind the teeth) accidentally cut his penis during oral sex. As a result, I swallowed a small quantity of his blood while his penis was inside the mouth.
I spat out the blood immediately and he has reassured me he's clean & clear from all STIs and HIV. I understand that I may be worried over nothing but this has never happened to me in the past and I am anxious that I may have put myself at a risk of some type of infection.
Hypothetically speaking, if the man was HIV+, can someone (in this scenario) be infected with HIV virus by swallowing a small quantity of infected blood?
Many thanks!
