Hello all, I am extremely nervous and although I've read all of the posts concerning oral sex not being a risk I am still questioning if my case is different. I recently engaged in oral sex with a transsexual off of craigslist anonymously. It was a very dark room. She performed very hard and vigorous oral sex on me and also a very deep rimjob. I also get acne and had some on my penis at the time. I also get hemorrhoids and may have had an inflamed hemorrhoid during rimming. Anyhow, she just informed me she tested positive for syphilis. I have heard that syphilis can negate the no risk for oral if she had an open chancre. Is there a chance i got HIV from this exposure? thank you
