Your situation involves personal contact with an object in air (vagina, saliva, mouth, etc. ). You will be happy to learn that you had no risk, because you can't get hiv from personal contact except unprotected penetrating vaginal or anal with a penis, neither of which you did and you didn't share hollow needles to inject with which is the only other way to acquire hiv - there are only 3 ways to get hiv. Analysis of large numbers of infected people over the 40 years of hiv history has proven that people don't get hiv in the way you are worried is a risk.
HIV is a fragile virus in air or saliva and is effectively instantly dead in either air or saliva so the WORST that could happen is dead virus rubbed you, and obviously anything which is dead cannot live again so you are good. Blood and cuts would not be relevant in your situation since the hiv has become effectively dead, so you don't have to worry about them to be sure that you are safe.
There is no reason for a person to test when they are safe. The advice took into consideration that the other person might be positive, so move on and enjoy life instead of thinking about this non-event. hiv prevention is straightforward since there are only 3 ways you can become infected, so next time you wonder if you had a risk, ask yourself this QUESTION. "Did I do any of the 3?" Then after you say "No, I didn't" you will know that it's time to move on back to your happy life.
No one got hiv from what you did during 40 years of hiv history and no one will get it in the next 40 years of your life either. You can do what you did any time and be safe.
You can't get hiv when you use a condom either.
Keep working with your doc to deal with your "might be an ulcer in esphagitis" since it is a waste of time for you to be googling hiv symptoms - you can't have hiv.
but the contact i had in this is unprotected insertive oral sex.i just want to be sure if esophagus ulcer is common in 20 to 30 year olds or is it a symotom of acute hiv generally?
Since you didn't answer the QUESTION I will do it for you here.>> No, there was no penetrating vaginal or anal sex for the oral sex and a hollow needle wasn't used for the oral sex, so I had no risk and should move on instead of wasting time asking if an impossible hiv infection occurred.
At this point your anxiety is a bit of a mental health problem so consider therapy if you can't stop thinking the impossible happened.
