Reread the advice on your Sept post. You have many posts about hiv and std so maybe you should stop going to these places since you end up so anxious afterwards that you keep asking the same questions as before.
We understand you may come from a part of the world where information for how HIV is transmitted isn't as available. You've asked about different exposures but you have to remember the ONLY ways that HIV is transmitted. These ways are unprotected vaginal or anal intercourse (penetrating) or sharing of IV drug needles. Unless you are writing about one of those ways, you will be told you had no risk including this time with an exposure of protected oral sex.
Oral sex is NEVER a risk even unprotected because saliva and air inactivate the virus. You can't touch the virus either. So, all scenarios that do not include the three ways people get HIV are no risk. That should serve the purpose to ease your mind with your sexual encounters. You used a condom ,that is safe sex. Keep doing that and you will never expose yourself to HIV.
