I recently had an encounter with an anonymous male (not a sex worker) and he performed very brief oral sex on me. He put my flaccid penis in his mouth for approximately 5 seconds, when I decided that I didn’t want to continue with the encounter. 

I don’t have any symptoms, but my anxiety and paranoia are at extreme levels (I’m married). I have my annual wellness visit coming up next week, but I am generally concerned about my exposure risks. Thank you!

Gonorrhea and, very, very rarely, chlamydia is occasionally acquired through receipt of oral sex,  Given we brevity of your exposure, your risk of acquiring these STI‘s is very low but to be entirely confident you were not infected, a urine test for gonorrhea and chlamydia taken any time more than 3 to 5 days following the exposure will conclusively prove whether you were infected or not. If your partner did not have oral lesions there is no meaningful risk for acquisition of Syphilis. 

I hope this response is helpful.  If a part is unclear or further clarification is needed, please don’t hesitate to use your up to two follow up questions for clarification. EWH 

I'll know definitively after my wellness visit next week (although, I'm thinking of getting tested today to calm my nerves a bit), but could there be non STI explanation for the discomfort? Feel free to tell me that my paranoia is driving me crazy!

Thanks again for all of the help!
