Kissing carries no significant risk of HIV or other STDs, with or without blood exposure, and I am unaware of any reports of transmission through mouth area bites. I suppose the risk in theory is a little higher than kissing without biting, but even doubling a virtually zero risk still leaves virtually zero risk. In any case, the statistical likelihood is low that the stripper is HIV infected. I don't recommend testing.
