Kissing with eyes wide open

As the title states I don't mean slightly open but widely open, I realized that when I kiss with the girl after a few seconds I just open them wide open and check around I don't even know why I do that.. some people says that If someone opens their eyes during kissing they don't like the other person or things like that but no It has nothing to do with It.. It do look weird from 3rd person perspective but I just don't know I feel like I'm vulnerable when I close my eyes during kissing
