A couple days ago I noticed a crater like blemish under the head of my penis, and a centimeter under that was a small domed blemish with a pencil point black dot in the center, I let it be to see what would happen. Now today, the crater like blemish is now scabbing and healing, but the other black dot blemish just turned into the same crater like spot, the black dot now not there. Also there are now several more black dot blemishes. Just need some insight as I don't currently have health insurance.
