I had sex with a guy last night. We didn't use a condom, but he said he had an STD test a month ago. I'm not worried about pregnancy because I have an IUD. Now I'm just freaking out thinking "what if?" He's in the Army and I know how they keep up with their soldiers - they won't allow you to deploy without having your wisdom teeth removed. They're serious about the health of their soldiers.
Can someone ease my mind? A little? Or did I really screw up?
