This answers all of your HIV questions, and if you can think of any more just reread about the 3. You had zero risk therefore testing is irrelevant to your situation because you had zero risk. HIV is a fragile virus, which is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.
Only 3 adult risks are the following:
1. unprotected penetrating vaginal with a penis
2. unprotected penetrating anal sex with a penis
3. sharing needles that you inject with.
The only way to get HIV is if you did one of the 3. The situation you describe is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. Doctors have calculated the risk from what you describe to be less than that of being hit by a meteor, therefore no one will get HIV from what you did in the next 40 years of your life either. The above HIV science is 40 years old and very well established, so no detail that you can add to your encounter will change it from zero risk.
If you didn't have one of the 3 then you are just worrying about your own hiv theory - which is unrealistic for you to think that can become reality - so you should move on back to your happy life instead.
You can read anything on the internet, including many other disease risks that you don't worry about today, so the first step to peace is to stop googling for death cold turkey.
Have you been here before under another name? It doesn't take long to read through some of the questions here and see the responses that never change stating that oral sex is not a risk for HIV transmission. Simply does not happen. If you wear a condom during vaginal or anal intercourse and don't share IV drug needles, you'll never have to worry about HIV. Saliva and air inactivate the virus and hence, oral is not a risk (no matter the state of your mouth's health).
Oral sex are not a risk for hiv infection,unprotected anal or vagina sex are indeed a risk.
