no, blood has to come in contact with a open sore, it takes about 2 litres of infected hiv/aids saliva to get it and then its only a 40% chance of getting it, or something like 40%, cant remember just finished the thing in school.
You actually paid attension! And, i though the q was, would the grl giving the blowjob get it. So, if there is a huge risk she will because the dick is in her mouth and the linning of the mouth tears very easily, making an infection of HIV much more liklier than vaginal sex.
