I recently received oral sex from a woman without a condom for what couldn't have been longer than a few minutes. I realized later (in better light) that this person had a mouth full of rotten teeth, most likely from methamphetimine use. I thought she had a tongue ring because i felt something scraping the bottom of my penis, I only realize now that it was her rotten teeth. I am concerned that this person, assuming heavy meth use, could be HIV positive and I would like to know what the risk of transmission would be in this scenario. Thanks for any help in advance.
