Hello Doctor,
8 weeks ago I had a sexual encounter with a transexual prostitute/escort. Her HIV status was apparently negative. I engaged in protected anal sex insertive, as well as unprotected oral sex insertive (she gave me a blowjob). I also french kissed her for a few minutes, the blowjob was also 5 to ten minutes, and the sex was very short as well. Three weeks later I noticed mild lymph node swelling in my groin area, then 4 days later I had mild night sweats and chills for a night or two. I also had what I think might have been ulcers on my gums, but it was also followed with a toothache around the area (i have bad dental hygiene). The lymph nodes were slightly painful to the touch but swelling decreased in a matter of days and was gone within a week. No other swelling.
I know that the act was substantially lower risk than most. I was tested at 27 days for an assortment of STIs including HIV (combo test) and it all came back as negative.
I was thinking of taking another next week to check for possible antibodies. I have never been with a transexual prostitute before this (never will again). Do I have anything to worry about?
