I had unprotected sex with a female about two months ago. Two days later I got two immediate semi decent sized red bumps on my penis head. Didn’t think anything of it. They formed into ulcers and then about 8 more ulcer bumps appeared on the shaft. I went to the doctor and he had them swabbed and took a urine test and both were negative for HPV. The bumps of my shaft practically vanished but the red scar like circles on my penis did not. They faded away but recently after sex they got a little bigger. They almost look like eczema spots but have a few little darker red spots in them. I’m worried. Could this be eczema?
