Pimples on my Penile shaft?

Starting about three weeks ago I started noticing small red colored pimple like manifestations on different portions of my shaft. I’ve noticed that are shiny when the light hits them but I didn’t have any irritation or burning. I also tried squeezing them to see if any pus came out but the pimples do not burst and see to be very firm. I have taken pictures of the last two and although they have faded there dry skin where they once were. Help? I will add pictures
