Hi doctor, I gave a man a handjob and washed my hands thoroughly a few minutes afterwards, but I noticed I had an open wound on my hand. It was an old wound that I had picked the scab off much earlier in the day, so it was not actively bleeding. What are my odds of getting HIV/any STD in this way? I did not perform oral, although I did kiss around his lower region. I tried to be very conscious to make sure I did not get any semen in my mouth. Do you think I need to be very concerned about my risk level in this situation? He said he was clean but I don't know him that well...
