2 days ago, i had protected oral sex with a commercial sex worker. Unfortunately , I also had a fresh sore
very near my anus. In the process, there was definite direct
, and prolonged contact from her tongue on the sore,the rest of my anal region and slightly into the opening of the anus. I am unware if there had been any blood in her mouth during this time. I would apppreciate it very much if you could assess my risks of contracting HIV in this encounter.
