Expert answer:
Syphilis is a Sexually Transmitted Disease (STD) that has an incubation time of approximately 14 days and the initial lesion is a cancer (wound) at the site of the contact, but as you have only had intercourse with a condom and the symptom described by you does not seems to be the typical Syphilis lesion, apparently not syphilis.
Seek a Urologist who will examine the injury, make the correct diagnosis and treatment.
