White spot on glans

Hello guys, I would like to ask you for help. I have this white spot on glans for a few months. No size change. Sometimes it is not visible. Seems it is something maybe underskin. Not sure if it is only some kind of gland/PPP/pigmentation/ not-serious stuff, or if it can be something worse? I am 32, circumsed 2,5 years ago. No STI/STD, no not-protective sex. Thank you
