About 4 months ago, I recieved oral sex from another man. A month ago, white spots appeared on the head of my penis. These spots are not raised at all and have not changed at all. They are the same texture as the surrounding area. It basically just looks like a discoloration under the skin. About 4 weeks after these spots appeared, my genitals started to itch, however this was also when the weather became much warmer. The itching is never on the head of the penis where the spots are, and is instead mainly on the shaft of the penis, which is also quite sensitive, or around the anus or scrotum, usually where there is pubic hair. I dont actually know if the spots and the itching are related at all. Does this sound anything like HPV? Should I get tested?
Also, about 1 week before the spots appeared, I was taking the antibiotic Cefdinir for a throat infection, which may have actually been mono.
