Ok like the title says, there s a build up of something on my glans, and I don t know what it is. It doesn t cover a large area, it s actually pretty small around 1.5cm by 0.5 cm (area wise) and then around 0.5mm thickness wise and it s located on the bottom part of the head on the left side. This area brings no irritation/pain ever and it s not white, it actually looks like my foreskin colour, so it s most likely not smegma . Also, I can pull my foreskin back perfectly and get all the necessary cleaning done back there.(I also shower once a day everyday) It s not really all that noticeable either. Additional details-When I was young I damaged the left side of my penis (not horribly) and due to this, it curves to the right slightly. Could it be scar tissue due to this?
