I have a partner diagnosed with syphilis, titer 1:4 April 2016 (injected once and doxyciycline 20 day, twice a day) .
I (bottoming) had sex with him without protection (anal, oral, msm) several times since Oct 2015, earlier at March 2016 I had tes HIV -, Syphilis -.
We continue practising sex (safer sex) using condom (anal), unprotected oral. I got my test July 2016,HIV & Syphilis negative. He had test August 2016, still the same Hiv negative and syphilis positive, but higher titer 1:8. He now is getting medication an injection and was asked to come back 3 month later.
1. How is my risk as a partner?
2. What should I do? Stop having sex with him?
3. I don't see any chancre/sore but might be I am wrong.
