I think that looks are somewhat important, especially when you're young. You've got to look at the guy sometimes, ya know? As we get older, our priorities and expectations change, so they become less important.
A guy can never be too tall! Unless he is like 7 feet, abnormal height. I am 5'6 and I like 5'10 guys and up but my husband is my height. He has a sense of humor and make me laugh daily, so I overlook his height.
