Is this an STI?

Patient: I think I may have an STI but I’m not sure. It started as one spot about 5mm away from the base of the penis but there now appear to be two more coming up near it. There is nothing actually on my genitalia so for though! The spot is kind of like a mole except its red and I don’t have any itching or any abnormal sensation.I have attached a close-up picture.Any help or advice would be greatly appreciated!Gerry
