Concerned about exposure

[Chargingup]

Dear All,
All data on the various HIV information providers, states that HIV via oral is zero to low risk. My exposure was performing oral on a guy, which would mean based on current information available that my risk was low.
I do have bleeding gums (not actively bleeding at the time of the BJ) and I do have a sore on my gum (a small one). I did not take any ejaculation directly into my mouth, but I did lick the penis shortly after ejaculation. The whole episode lasted around 5 minutes, it wasn't rough, like deep throat... just mild fellatio. Based on the information that I have provided, could you kindly provide a risk assessment based on your current knowledge and understanding, in particular, I'm  interested to know how much damage to the mouth would be needed for infection to potentially occur and, would a significant amount of infected ejaculate  need to be in the mouth i.e. a mouthful!.

The only risks for HIV transmission in adults are: ;
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles.

Giving oral sex, with or without cuts/abrasions, isn't considered a risk for HIV transmission.  Sites that list oral sex as "extremely low risk" are largely commenting on the theoretical possibility of transmission via this method, and HIV specialists do not recommend testing after an oral event.

Many Thanks for your response, you have put my mind at ease as I was I little concerned that it may be a low risk.
