Hi,
I have had unprotected sex about 3 weeks ago. (note: I am uncircumcised)
I noticed that my penis was itchy and had multiple red spots on the head of the penis. After a few days, the spots went away and then I noticed one very pimple-like sore appear on the tip of my foreskin.
There has been a burning sensation whenever urinating, and the pimple had some white puss coming out of it (like any other pimple).
I have already scheduled an appointment with a doctor this Friday, but I also want another doctor's opinion. It sounds like it could be syphilis or a "common" infection. Thoughts?
