Manage sex life with partner with syphilis

[Ranger90]

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.

I did have sex with him several days before his last test, protected anal, and unprotected oral, I don't see sore or anything.

Finger crossed, He might be in late syphilis so it's not contagious.

Can hickey pass stds? syphilis

I dont see why you need testing again. your negative and if you have not had any skin contact with him since then, your still negative.

His test result
Initial test rpr 1:4,Tpha positive  (April 2016)
Another test rpr 1:8 Tpha positive (August 2016)

Mine
March 2016,negative hiv and syphilis
July 2016,negative hiv and syphilis

My concerns is whether I should get tested again because of his increasing titer from 1:4 to 1:8?

Thank you

Hi, when a person test positive for syphilis they need a second test to confirm and a .1.4 is very low so there a chance they did not have syphilis in the first place. Your questions are valid but the approach to syphilis is not. He needs a second confirmation test.
Stop having sex until a diffinate confirmation is done.
