Hi Doctor. I had unprotected sex with my girlfriend a week ago (i ve only had sexual relationships with her for almost 4 years), and 2 days ago, i found out i had these: - mildly burning sensation while peeing - light fever for a day - sore throat that has been ongoing - A single pimple-like bum on the shaft, i did not pop it, but it is now a scab - I checked my urine. It is light colored and foamy, but it does not smell foul It is important to note that before this happened, I slept without clothes once, and i have not shaved my pubic hair . What could this mean? STD, or just an infection?
