No risk with oral so it doesn't matter how many std or bleeding factors you had or might have, it is still zero risk. Only unprotected anal or vaginal is a risk so you can move on from hiv.
Well, you're busy! So almost every day of the month, you hook up and give a stranger oral sex? Is it a compulsion of some sort? That may be something to discuss with a mental health worker. But with regards to HIV, this is not going to transmit HIV to you. HIV is really a fragile virus and transfers in specific ways. People that get HIV get it from having unprotected vaginal or anal sex or sharing IV drug needles. Air and saliva inactivate the virus.
