I got drunk and stupidly ended up giving mutual unprotected oral sex to a Thai sex worker (male) four days ago. The encounter lasted 30 minutes or so, I think there was pre-cum, but neither of us ejaculated. I am going mad with worry. I know I was hiv negative as I had a recent test and this is a solitary. The web has a lot of conflicting information regarding the chances of picking up hiv or another disease from this encounter or something like it. Any advice, comments or encouragement would be appreciated.
