there are many different strains of HIV. You can get a different strain. If you are undetectable and they are not, you CAN get reinfected, and your current medication will no longer work. This is with anal sex anyway.
From my understanding, oral sex, no, you are pretty much safe, unless you have open wounds in your mouth. Saliva and your stomach acid kills HIV, or makes the HIV in active. I would have to reread that information myself, but I believe that's what I have read and been told.

Here is what I found:
The overall risk of getting HIV through oral sex is extremely low to negligible. Major health organizations, including the CDC, classify oral sex as an activity carrying little to no risk for HIV transmission compared to anal or vaginal intercourse.
Factors Affecting Risk Level.
While the baseline risk is nearly zero, specific variables influence transmission likelihood:Undetectable Viral Load (U=U): If the partner living with HIV is on effective antiretroviral therapy (ART) and maintains an undetectable viral load, the risk of transmitting HIV through any type of sex—including oral sex—is zero.
Receptive vs. Insertive:
Giving oral sex on a penis (receptive fellatio) carries a slightly higher potential risk than receiving oral sex or performing oral sex on a vagina (cunnilingus), though the overall chance remains very low in all cases.
Co-factors that Increase Risk:
The risk increases slightly if there are open sores or cuts in the mouth or on the genitals, bleeding gums, advanced gum disease, active oral/genital STIs (like herpes or syphilis), or direct exposure to pre-cum or semen in the presence of damaged mucosal tissue.
Biological Protections.
The mouth is naturally resistant to HIV transmission:
Saliva Composition:
Human saliva contains specialized enzymes and proteins (such as secretory leukocyte protease inhibitor) that actively inhibit HIV.
Tissue Structure:
The lining of the mouth and throat is thicker and far less susceptible to the virus than the delicate tissues of the vagina or rectum.
Other Considerations
While the HIV risk from oral sex is minimal, other sexually transmitted infections (STIs)—such as herpes, gonorrhea, chlamydia, syphilis, and HPV—are transmitted much more easily through oral sex. Using barrier methods (like unlubricated condoms or dental dams) effectively prevents the spread of STIs during oral sex. If a potential exposure occurred within the last 72 hours and there is severe concern, consult a healthcare provider promptly to evaluate whether Post-Exposure Prophylaxis (PEP) or general STI screening is recommended.

@A myHIVteam Member no worries. Our ARVs protect us as well. Consider adding doxyPEP though as needed. Your HIV doc can prescribe.
