A few weeks ago (November 26), I made a stupid drunken decision and performed cunnigulus for about 15 minutes on a coworker at her hotel after a business conference in Germany. The contact was with her clitoris only and I did not put my tongue inside the vagina. However, I had bitten the side of my tongue fairly hard about 30 HOURS beforehand. At the time of the cunnigulus, the tongue bite was still very visible and tender, but not bleeding and didn't burn like a canker sore.
So this week I coincidentally heard a story from another coworker about this woman being quite promiscuous. I don't doubt it since she would clearly have been ok with unprotected sex with me.
I've read many posts on this forum about cunnigulus carrying a low risk for the person performing it, but I'm worried about my bitten tongue and that she could have HIV. I would feel much more reassured to know specifically why the risk is deemed to be low or non-existent. Is there something about the saliva that inhibits HIV even with cuts in the mouth?
