What Causes Dark Spot On Penis Shaft?

Good morning,
I am curious about a dark spot that appeared a couple months ago on the shaft of my penis. I am brown skinned and the spot appears to be darker brown and is the circumference of a pea. There is no texture to it to speak of. No rash, no pain, no discharge... nothing. Then a couple days ago I developed two sores in my mouth. One on the ribbed roof of my mouth and the other on the gum/cheek just past my last molar. At first I figured I had eaten too much citrus, but now my mind is playing games. I wonder if it is an STD like syphilis.Ideas? I'm very distracted now. Thank you very much.
