I had unprotected anal sex with a stranger. It was accidental, and in the heat of the moment. It went in, and before anything could happen it came out. No climax, or anything. Literally a few seconds. I developed a UTI, and it went away after a full round of antibiotics. My doctor didn't do any std tests, and it seems as though my UTI is gone. I'm not sure if I'm just hyper aware of sensation in my penis after the intense pain of a UTI, and my own paranoia- but I think something is still wrong. I'm peeing normally, and it doesn't burn or anything. Is it possible to get an std from such a quick insertion and removal? Again, no climax or anything... It was a few seconds and we both decided to stop. Help I'm paranoid and anxious and scared!
