Any tissue inflammation probably increases the risk of HIV transmission if exposed to HIV-infected secretions, so in theory there might be some microscopically increased risk. But the odds are extremely low. You also might get killed by lightning someday. Neither risk is sufficient to lose any sleep over it.

Tank you and I apologize for the inappropriate behavior.
And a word to poster concerned about the nipple biting: I am not an expert but even I know that you have nothing to worry about in that instance. Consider what the doctor said to me, I might as well worry about being hit by lightning, and I had much more exposure than you did. Don't torture yourself like this, it just isn't worth it. Good luck.
I know this is a new question, but please answer. It is my last question and I am worried about it.
Biting is low risk for HIV transmission; there is little or no infectious HIV in the mouth. Nobody gets HIV by oral-breast contact.
