Something on glans

A few days ago I noticed a red area appear on my penis. I’ve attached pictures that show its progression over the past 4 days. it has never been sore or itched, and never was a blister. Two more spots have appeared, and the latest towards the bottom of my glans is more brown than red and doesn’t appear to be heading to a blister or ulcer. Im working on posting my pics, it says the file size is too big.
