Hi doc, 3 days ago i had unprotected oral sex from a girl i just meet (1night stand) today, 3 days later I noticed tiny red bumps/spots (rash like) on penis head (10-15 of them). No pain no itching, no trouble peeing, the rim of the penis does look little purple, uncircumcised. Worried that it might be some std after searching online (we know how that goes).
