Spot/bomb on penis shaft

Last weekend I noticed this spot on my penis shaft. I have kept an eye on it and i dont think it has got any bigger, what could it be?

It is small, no bigger than a milimeter or 2 across, skin colored and has me very worried!

It's hard to offer useful advice without seeing a picture.
