Are you sexually active?
If this is as much of the head of your penis that you can expose then that would not be completely normal?
However, many men go throughout their lives not even being able to expose this much of their penis head. Maybe do an internet search for pictures / diagrams of the glans / head of the penis and see how yours compares.
