I had unprotected sex with a guy that I have known for about 2 weeks, I know this was stupid of me. We only had sex twice and the first time we used a condom and the second time we didn't, but he did pull it out before he came. I know even with him pulling out I'm still at risk, but my question is how likely is it that I could have contracted HIV from him? I have asked him about his status and he said that he is clean and that he is a Medical Technician and that they get tested all the time, but I don't see a job regularly testing their employees for HIV and STD'S.
