I have had unprotected (receptive) oral sex three weeks ago, during which I had scratched my penis. There was no bleeding and no scars at that point but I have been feeling a stinging pain at that spot. I also have a little itchiness in the groin area since then. There is no pain while urination. Is this indicative of Chlamydia or any other
STD/STI? If so what tests must be done for Chlamydia and what other STI/STD testing must be done? Any help would be appreciated. Thank you!
