I think it's a pretty rare occurance for a male to catch HIV from a female giving him a blowjob. She would have to have pretty bad bleeding gums for even the virus to come in contact with your skin. From everything that's been written and said, you can't catch HIV through saliva, or if you can.. it's EXTREMELY rare. Both people would have to have open sores in their mouths and bleeding gums. But I guess the same can be said for females... I don't think it's close to possible for a female to catch HIV from a guy going down on her.

But yes, I worry about HIV all the time. I will not give blowjobs to any guys if I know they haven't been tested. And just the mere fact of thinking about having sex with an HIV positive person scares the shit out of me. That's probably why I don't do one-night stands.
