I would like to add that I did have some dry skin on my penis, however there did not appear to be any visible cuts or breaks.

One other thing, I wanted to add that I am not asking for a therapy "peace of mind" testing scenario (I have also seen that backfire where people start testing every 5 days for 12 months). If you were in my shoes, or advising a patient, what would you advise? I'm looking to get back to normal life. I made a mistake that I won' be repeating and would like to resume life with my wife.

Last piece of information, my last negative test (for life insurance) was from mid January 2018. This is the only risk before or since that test.

Welcome to the forum. Thanks for your confidence in our services.---

Thank you Doctor for the quick response. To clarify for you, I was treated with CEFTRIAXONE-CEFTRIAXONE SODIUM at 250 MG as well as a single dose of ZITHROMAX-AZITHROMYCIN at 500 MG. I was told that this would not do anything if syphilis was present and that I would need a penicillin shot to treat that if it were to present. I mistyped in my original post, the syphilis test would occur next week on Tuesday, which is 16 days after possible exposure. Believe me, I am not looking to go through anymore undue stress, but I also didn't want to ignore any risks at the same time. Is there evidence that this combination is sufficient in eliminating syphilis as well?

You were misinformed or misunderstood what you were told about syphilis. Ceftriaxone for sure and azithromycin probably would abort incubating syphilis if you had been exposed. Having had those treatments, you cannot possibly have syphilis from this exposure and should not have any future testing for it. (On top of which, there was absolutely no chance of syphilis from the exposure described.) You could consider printing out this thread to give your clinic -- this perspective on syphilis and its prevention is the normal one in every STD clinic and among all STD experts.)---

Thank you so much for that, in fact I will be calling them to inform them shortly and will print this out for their records. Nothing is worse than being misinformed when you are hoping to be getting information from an expert.

The notion of HIV risk from exposure to "a single drop of blood" is technically true, and nobody can say the risk is zero. And some providers and even many public health programs prefer to err on the side of caution, suggesting that any exposure at all warrants serious concern and testing. But the fact remains that the busiest HIV/AIDS clinics have essentially no patients whose only reported risk was this sort of trivial exposure. Everybody has the standard risks, i.e. unprotected sex with known infected partners, anal sex between men, shared drug injection equipment, etc. The data show that the risk of HIV from a single episode of unprotected vaginal sex with an infected female partner is around once for every 2,500 exposures; and that sex during menstruation (exposure to much more than "a drop" of blood) does not elevate that risk. Another good example is that the household contacts of people with HIV never catch it, even after many years of sharing kitchens, toilets, and often razors or other sharp instruments with the infected person -- even though such day to day contacts must from time to time include minor blood exposures.---
