Hi. I am (was) completely clean. A week ago, I gave a questionable man a b-l-o-w-j-o-b without a condom. He said he was clean, but you never know. I stopped before he ejaculated. I was just wondering what are my chances of getting hiv/std from him if he had no symptoms, did not ejaculate, there was only oral, and I have are no std symptoms after a week?
