White spot on the penis head

I have white spot on my penis head can someone help me please

They may simply be enlarged glands, but you should provide more info to give clues…
How old are you?
Are you sexually active and/or masturbating?
How long have these bumps been there?
Are you suffering any other symptoms?
Are you applying something on it (creams, soaps etc)?

I am 23 years old
yes I am sexually active and I had once unproctected sex with my girlfriend
so I am really worried

Pls someone help me
