Men are fair and they have learned not to personalize anger - they can disagree with you and argue to the bone but afterward they still consider you a nice person with whom the underlying human relationship need not be altered.
My personal belief is that you carry your own water in a relationship. If you see a girl and you think she's hot that's a very human reaction but you don't go and tell your spouse that you know? So in one way it's how you behave.
