Am I being disrespectful toward my wife?

When we are out together I am always looking at other women. I just can't help it! I have to keep looking and look and look I cannot stop lol!! Yea they notice I'm checking them out while I have my wife & kid with me..and yea I would love to F**** them if given the chance, but that's not gonna happen...my wife thinks it's okay for me to look all I want as long as she isn't with me, but feels it's humiliating towards her when I do it when we are together. I think not, I'm a man and I'm sure every other man feels the same. Who is right??
