Hello. A week ago I developed a mouth ulcer that I initially thought was a result of biting myself on the inner side of the cheek. I went to get it checked yesterday and the dr sent me to test for syphilis / HIV given my sexual history. Briefly:
Two encounters with men I met online that included deep kissing, fellatio on both sides and rimming.
Tomorrow morning I'm going to get the tests done but I wanted to assess the risk I have in this scenario considering I had a mouth lesion that may have gone unnoticed. Also what is the risk if I do test positive for syphilis. I heard HIV is easier to pass when other STDs are present.
Thank you in advance.
