about 6 weeks i was at a strip club. when i was sitting at the bar a stripper came up to me and started kissing me and i pulled away after a couple of seconds after a minute she kissed me again and i pulled away again. when i got home that night i noticed a bloody cut on my bottom lip. im not sure when it happened, if i bit it or she bit it all i know is that it was bleeding. what are my chances of contracting hiv if it was there before i kissed her or happened while i kissed her?
