If a condom fails it is a large rip down the seam and it hangs in tatters so that didn't happen.
You had no risk of HIV and are so safe that you don't need to test.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from 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 adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with but you didn't do that so you had no risk. This sentence is all you need to know to protect yourself against HIV.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from oral activities. The above HIV science is 40 years old and very well established so nothing you can add will make your situation a risk.
No one got HIV from oral activities in 40 years of HIV history, so likely no one will in the next 40 years of your life either.
There is an std forum for best answers about std.
It is your guilt, more than your risk that that terrifies you. Since you bought condom yourself, so there may not be any quality issue because you definitely picked up some international brand.
There is also a very strong possibility that it did not fail because had it failed, it would have been catastrophic and too obvious to ignore.
Unprotected sex either way is not a risk either. Based on these facts, it can safely be assumed that you were not exposed to HIV.
