How do you keep your man to stay faithful to you?

My husband loves me and I love him. We have been married almost 10 years and I can honestly say he has never cheated on me. How do I keep my man faithful? I don't really know. We hardly, if ever, argue. I don't nitpick the small things. We are always open and honest with one another. Also, he gets "it" whenever he wants "it". I think a woman just needs to be loving and attentive. Understanding and caring. Stop sweating the small stuff. Don't meet him at the door with your horror stories of your day. Rather ask him how his day was and actually listen. The list can go on and on. If he gets all the attention he needs at home, in all ways, he won't need to go somewhere else to find it.
