10 days ago I had a sexual encounter with a TS escort. There was a brief bit of receptive anal sex, protection was used and there was no ejaculation. I got tested, and all things came back clean, however I am still experiencing some dull pain in my rectum area. This was my first (and last) experience with this, so I wanted to poll the board here. Am I looking at an STD concern, even though I tested negative for chlamydia, syph, and Ghon? (Blood and urine test). Could this be some sort of normal pain that’s experienced with first time anal sex? If so how long should I expect pain to last? Potentially some sort of fissure?
Thanks for comments in advance.
