I've had an STD before but I've been with this girl for four months now and recently I've had a burning sensation and let's be clear I haven't stepped out and cheated on her I went to the doctor they said it wasn't an UTI they gave me a shot and said they will call back in a couple days what do I have because I don't feel like I felt before when I had and STD it's just a lil bit of burning and frequent pissin
