I received an unprotected blowjob from a girl I don't know very well, but who is regarded as being very promiscuous. I noticed approximately 2-3 months later that I have a small black dot on the edge of the head of my penis. I have not noticed this dot before, but I never inspected myself that closely. It's worth noting that I have a brown spot or two on the shaft of my penis that I have had for years and some very, very slight brown pigmentation on my head as well. However, nothing that resembles this small black dot. I'm in a committed relationship so My rational side is telling me that I'm paranoid. With that said, is there any chance that the small black dot is a genital wart? It isn't rough and it doesn't appear to be elevated. Is there any chance that it will grow into a wart and I just noticed it before it blossomed? Below is a link to a photo I uploaded of the dot. Please advise. Thanks.
