I would like to consult. The other party has been taking the drug for four years, and the value from half a year to August 23 has always been less than 20. The act that occurred was active oral sex, no ejaculation occurred, but licked its pre-ejaculated semen. At 9.30, there was an ulcer in the mouth, the behavior occurred in 10.2, there were also some gums when brushing teeth, the ulcer did not bleed, there was a false membrane on the top, I want to ask about this situation, thank you very much.
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 ANSWER "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 from hiv.
The other person's status is irrelevant when you have no exposure to live virus.
If you still have questions about your risk, after reading all of the above, then it is because you didn't answer the QUESTION above.
