Do romantic thoughts or sexual thoughts go through that a guy's head when he always stares at a girl?

So if you stare at a girl pretty hard all the time and eye lock here and there, what goes through your heads?

Obviously you find the girl cute / pretty but do you think of romantic thoughts or dirty thoughts or just no thoughts?

Give me your experiences and opinions?
