Hello, please don't ridicule me for this or attempt to teach me a lesson that I can swear to you I've already learned.
Two nights ago I had unprotected gay sex with a 20-year-old man and let him penetrate me without protection for a good amount of time (probably 15 minutes). We had never met before, and I have no way of contacting him. Beforehand, I asked him if he was "clean," and he responded by showing me some papers from a week beforehand where he had been tested. I didn't look at them very well at all, but decided to trust him in the moment. Now, however, I cannot help but feel concerned and worried about the potential contraction of some sort of STD. What are my odds here, and what should I do?
Clearly, I will never have unprotected sex again. This was a one-time deal. Thank you for any advice.
