My Girlfriend Has Just Tested Positive For Chlamydia And Gonorrhea.

My girlfriend has just tested positive for chlamydia and gonorrhea. We didn't have actual sex, I just put my penis in and out twice with no condom. I have not had any sexual partners before this, and she says she hasn't either. How is it possible she has both diseases with no sexual partner but me? And what are the chances of me getting those diseases?
