First to start off with my risks. A few erotic massages with handjobs and a few blowjobs from men and women, mostly women (always with condom and always with them only sucking the tip, because I’m a hypochondriac freak)

Now, I started checking yearly back in 2021 for STDs and always had negative rpr screens and other STDs as well negativo . 

But, I have acne, and usually am on and off doxycycline for this.

My concern is, could the doxycycline have been masking my rpr to keep it negative?

The reason I ask is because of this, I have a new clinic that does treeponoma reverse algorithm testing (I think, lol, new to this)

The lab order says treponoma EIA tests.

My concern is, what if I previously had syphilis (from above encounters) that the doxy kept the rpr negative? And now, what if the treponoma eia is positive (because to my understanding, it remains positive no matter what after infection) How the heck do I explain this to the mother of my children?

The new lab order/test really freaked me out. Do you think my risk was low that I never contracted syphilis anyways? Can I expect negative treponoma cia result as well based off these risks?

Please help. I hope I was clear. English isn’t my first language.

Lastly, are the above related risks any worry in regards to hiv and hep c, as well

As chlamydia?
