Lucky...hmmmm....you have mentioned him laying his head on your hip and you stroking his face and hair before, like this is a regular occurance.
It sounds very sweet and motherly of you to do this for him...but that might not be what is best in your case.
I think you should back off from types of intimacy that seem too "mommy" toward him. Instead, offer to rub his big muscly shoulders, and tell him how much you are enjoying it while you do it. Or offer to rub his temples, but stand directly in front of him while you do it so he is faced with your bosom (ie: temptation). Or rub his feet, but look directly in his eyes while you do it and tell him how hard you know he works, etc. Do things that give him your softness and intimacy, but only do things that remind him you are a woman and he is your husband, not your child.
On the other hand, making him dinner with his fave beers is perfect wife behavior. Two thumbs up on that one!
Or if you wanted to be a girl gone wild, you could have slipped your breast into his lips while he was resting his head on your hip instead of touching his face and hair....oops! Is that too naugthy of me?
