Hello, I have a quick question. 72 hours ago I had a sexual encounter with a guy (I am gay). He told me he was negative but after we fooled around, he told me he's positive. I said "no your not" and he reaches in his bag and pulls out his altrla(spelled incorrectly) and I was shocked. He did oral sex to me, I didn't give him oral, we didnt kiss, but he did put his dick in my anus just the head for less that 2 minutes. Then I put the top of my head in him for less than two minutes. Both of us didn't ejaculate in the anus. We both had lube BUT WAS NOT WEARING ANY CONDOMS. I went to the clinic the next day told them my story and they said they couldn't give me the pep. I am very stressed and scared. Can you please tell me what are the chances of me getting hiv/aids?
