If you cannot be a honest, loyal husband and control your urges, and stay within the boundaries of good behavior, you have no business being married! Its one thing to have desires, its an entirely different thing to act on them. I highly suggest you discuss boundaries with you wife, before things cross th line, and you find yourself explaining your online/personal behavior. That's why you are married, to talk to her about your innermost desires, and feelings, and get things worked out in your minds what's best for you both.

To give in to those desires impulsively, is a disaster waiting to happen.
