Can HIV Be Contracted Through Protected Sex?

Question: I had sex several times (10 times) with different prostitutes with protected condom about 12 weeks ago. I did lick their vagina for less than 30 seconds, and my mouth did not have any wound (only 3 times after that I did not have oral sex with the next ones). They did lick my part too, also less than 30 seconds. After that I used condom to have sex, and always came pretty fast about 1 or 3 mins. What is the probability to have HIV from that? I went to a doctor to ask, he said I had no chance to have HIV. But now I am having a little dry cough for half a month now, the dry cough is not constantly only several times during a day mostly after I wake up. And my body have a few small red dots not itchy. I had a 4th generation HIV rapid Test and along with other STDs screening test at 9 weeks. They were all negative. My clinic doctor told me that the results were good and I should not worry about that. But now my dry cough have disappeared yet. I want to ask can I rely on that result. How accurate that test compare to the DUO test? Should I stop worry and move on to live my life? Should I have another test to ensure, and can the result change to positive? I am so tired of this.

Please advise me, I am very stressful right now, usually feel tired every time I think about it.

Thank you so much. I think I should learn how to forget about this. Cause me so much headache. The reason you recommend me to go have another test is to release my anxiety, right, it is not because that I have risk and need a test.

Thank you so much. I am glad there always are people like you around to help out others. God blesses you.
