Hi did you end up getting a diagnosis as to what happened?
Hi my friend,
As this is your first encounter the risks are close to zero. So, first relax. Anxiety also can cause pain in muscles. And the pain in the urethra can cause by scrach during oral.
But, to confirm your std status, you can perform,
Urine PCR tests for gonorrhea and clamydia 12 days after the exposure, VDRL and TPHA for syphilis , HEP A, B after 6 weeks of the exposure and HSV 1/2 for herpes, HEP C and HIV ab test after 90 days of exposure. Many people recieved all negative results after similar situation. So, I feel, you will recieve negative results as well. Please update me with your test results. Good Luck.
