.Ok, thanks. One last question, I was reading the tips on the site about myths about HIV, and it said there might have been a couple incidents where someone got HIV through fellatio performed on another person that had HIV. If everyone is adament that it can't happen, then why would it mention that there were probably a few cases. If so, what could have caused those persons to have gotten HIV? Perhaps a bad sore throat, bad gums, etc? .
