About 10 days ago i made terrible mistake of having unprotected insertive anal sex with another man who's hiv status is unknown. The initial act (anal sex) was protected and i was the top (im a total top). After we finished we stopped for about 30-45 min and we decided to go again but this time without a condom. The act last about 3-4min. He assured me over and over that he is negative but i still have doubts. Knowing that it is too soon for a conclusive test result, today i went for an hiv test which came back negative. What are the odds of me catching hiv from this encounter??? I am extremely afraid!
