Is it possible for my girlfriend to get an std from giving me a BJ if I have never had an std?

I don't think it's possible, but some doctors say that when u sleep with people, or have oral sex with them, u sleep with all the other people they have been with. U have heard that saying? Well, another thing I have heard is that guys can carry certain std's even if they show no signs or symptoms. Guys can be carriers of STD"s that women have given them in the past. I just would say that you two should go to the clinic just to be sure. She can possibly get a bacterial infection in her throat as well.
