Yesterday, I went to cruise bar where I received oral sex from a guy. At the end, when I was leaving, he told me another guy ejaculated in his mouth just two minutes before he started doing oral sex on me. As I had talked with him a few sentences before we actually engaged in the sexual activity, I don't think he had his mouth full of fluids, but it might be still the case. In this circumstance, what is the likelihood of contracting HIV on a circumcised penis by indirect contact of semen inside someone's mouth?
Thank you! Very anxious here.
