I am a white woman in my 30's from the southern region of the United States.
My boyfriend and I split up for about a month, begining in October, 2011. We reconcilled in mid November, 2011 (about 5-6 weeks ago).
During the separation, he had an unprotected sexual encounter with a woman, which amounted to two acts of vaginal sex (both unprotected).
I was not made aware of this encounter until after he and I had unprotected sex (the relationship between he and I is 4 years on, and he had negative result blood tests prior to any unprotected activity between us 14 months ago).
At my annual ob/gyn appointment on Dec. 14 (6 days ago), I informed my doctor of the situation, and he took blood samples. Yesterday, I learned that I have contracted Syphilis. I am waiting to be referred to a specialist.
My question is this... I know that these activities have put both he and I at risk for HIV. Is the risk of HIV higher due to the syphilis, or since he had not yet developed ulcers, is it irrelevant?
