Last week, a girl did a handjob (masturbation) on my penis, I know it will not be inflected even if she is an HIV carrier because there is no secretion or blood exchange. However, my case is her hands were unclean and dirty, which were moist with the semen from another man who might be an HIV carrier. I can feel the squishy fluid. As we just left a pub, and everyone was drunk, I just saw she masturbates another man's penis before she did a handjob (masturbation) on me. Thus, will I get any risk of HIV transmission? I am very nervous about it. Can any experts or doctors answer my question? Many thanks!!
