Neither can you get HIV from oral sex nor from condom protected vaginal / anal intercourse. You didn't have a risk. No testing required.
Whatever you read was certainly not credible source of information. Your actual problem could be guilt or fear of disease or some other emotional issues, if it bothers you too much see a counselor. HIV is not your concern.
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.
You can't get hiv since you used the condom. You can find anything on the internet because some sites use theoretical risks that have never manifested in real life. If you continue to google for death you will find someone who will tell you that you can die from anything you plan to do in the next 10 minutes.
