So, my girlfriend and I had protected sex, as I used a condom. About a week later, I started experiencing burning during urination and then later, discharge. There's no blood in my urine, just occasional discharge. These are my only symptoms. The discharge wasn't immediate, but developed later on. We have had unprotected sex before, but back then, I didn't experience any symptoms.(yes I know, you don't need to experience symptoms to have an STD). I got Chlamydia about 5 years ago, but it was treated properly. Could there be a flare up from that? I'm just confused. I also really hope I don't give my girlfriend an STD. She is so wonderful.
