Welcome to the HIV forum.
Questions about about oral sex an HIV risk are among the most common questions here. Responding first to the title you chose for your question -- "Oral sex/broken condom" -- my response is that for fellatio, the risk for the oral partner is very low and that for the penile partner is so low that there are no clearly documented cases of known transmission. That's without a condom. So unless there is surprising in formation in the question itself, most likely there is no HIV risk here.
Now I have read beyond the title. Guess what? In addition to the low risk for fellatio, there has never been even a suspected case of transmission by cunnilingus, in either direction. The main problem, it seems to me, is that you have not paid much attention to the professional credentials of the websites you have searched. You wrote "I was under belief, maybe incorrectly, that no real risk for recipient and very low risk for the active participant." In fact, your original belif was exactly correct. If you were to prove to have caught HIV from these events, you would be the very first case in the world!
Since you are concerned, I agree you should have an HIV test. Not because I believe there really was some risk, but because if you are typical for persons who ask questions here, my reassurance won't entirely settle your fears -- i.e., you'll probably be further reassured by a negative test result. Assuming there are no other risks you don't mention, you can expect the test to be negative.
