I last had sex a little less than a month ago. My partner says she was clean and I believe her, though now these 4 white dots that look like the white head of a pimple have show up on the bottom left side on the shaft of my penis.
They're tiny, stick a pin through a piece of paper and the hole in the paper is about how big they are.

They're painless and just barely elevated. I even have a dot like that on my face but I'm used to getting pimples there. These dots are also spread out like a line going up Should I get tested?
