Just two week ago, I had a sexual contact with a sexual worker in Berlin (a German lady). I massaged
her, licked her breasts
, and she massaged my penis with her fingers and gave me a protected fellatio, and we had a protected sex.
Because I got very nervous, I went to a doctor for STD tests 14 days after this sexual contact. I had hepatitis B and syphilis blood tests (RPR and TPHA), and tests for gonorrhoea and chlamydia at throat. All clear, except for syphilis RPR test, which was positive.
