Upon the penis skin after the drynes it makes small circle spots and colour is changing and looks like wound healed area. Also i got broken skin in my back pass area and i used cavilon spray and it gets healed. But in the penis the dryness and duly when i try to pull the foreskin its get more tight and breaks the skin.
