When assessing the risk of sexually transmitted infections (STIs) after engaging in unprotected oral and vaginal sex, it is essential to consider several factors, including the types of sexual activities involved, the presence of any symptoms, and the timing of STI testing.

Firstly, unprotected oral sex can carry a moderate risk for STIs, particularly if there are cuts or sores in the mouth or throat, or if the partner has an active infection. Common STIs that can be transmitted through oral sex include gonorrhea, chlamydia, syphilis, and herpes. The risk of HIV transmission through oral sex is generally considered lower than through vaginal or anal sex, but it is not zero, especially if there are open sores or bleeding gums.

In your case, you mentioned that you had unprotected oral and vaginal sex and that it has been 79 days since the last sexual encounter. You have also undergone testing for syphilis, HIV, chlamydia, herpes, and HPV, with negative results for syphilis and HIV so far. It is important to note that while a negative HIV test at 79 days is reassuring, it is still recommended to retest at the three-month mark for conclusive results, as it can take up to 90 days for HIV antibodies to become detectable in some individuals.

Regarding the other STIs, the incubation periods can vary. For example, chlamydia and gonorrhea can typically be detected within a week or two after exposure, while herpes may take longer to show up, often between 2 to 12 days for initial outbreaks. HPV testing is more complex, as many people may carry the virus without showing symptoms, and it can take years for any related health issues to develop.

If all your STI tests return negative results, it significantly reduces the likelihood of having contracted an STI from the encounters you described. However, it is crucial to consider that some STIs may not be detected immediately after exposure, and follow-up testing is often recommended. For instance, retesting for chlamydia and gonorrhea is usually advised about a week after potential exposure, while herpes testing may be suggested if symptoms develop later.

In addition to testing, it is essential to monitor for any symptoms that may arise in the future, such as unusual discharge, sores, or pain during urination. If you experience any concerning symptoms, it is advisable to consult a healthcare provider promptly.

In conclusion, while your current negative test results are encouraging, it is prudent to follow up with additional testing at the three-month mark for HIV and to remain vigilant for any symptoms of STIs. Practicing safer sex in the future, such as using condoms and dental dams, can significantly reduce the risk of STIs. If you have any further concerns or questions, do not hesitate to reach out to a healthcare professional for personalized advice and support.
