Have sex more often. A man can have sex when he is tired, sick, or damn near dead. Men use sexual interaction as their main form of expression of affection.
Ask him to tell you some sexual fantasies that he wants to check off his list before he dies and fulfill some that are not too weird. Trust me; some of them will be weird. Men are sexual freaks. Don't take offense at his weird ones or he won't share any with you in the future.
For one weekend a month, have the “honey do” list be sexual. This is your chance to throw in a few requests.
Be amused and flattered when he constantly tries to get a glimpse of your naked loveliness instead of being annoyed. He loves your body.
When he is walking around naked, take notice as if he were Brad Pitt (or your favorite fantasy man). He thinks he looks good all the time, and if a book or the TV is more interesting you'll hurt his feelings.
Stroke his ego in a genuine way. Men are big babies.
Support his sporting endeavors and be proud of any accomplishment in any sport. In our hunter gatherer days the men who were the best warriors and hunters were the most desirable. Now, we have sports.
Praise him for little things that you wouldn't think need to be mentioned. Remember, men are big babies and love praise.
When he does more around the house make a big deal about it even if he doesn't return the favor. Remember, he probably thinks he is doing your job for you.
If he cooks for you, eat it, and praise the effort. He thinks he is a great cook.
Remember the following:
Men think about sex all the time. It's almost all they think about. They aren't prepared for the logarithmic decrease in sexual frequency that can come with time, children, stress, and health issues. Almost every man I've ever talked to wants more sex, more support from their spouse, and more praise and less criticism from their partner. If your man isn't always after you, that is not normal, unless he is disabled, drinking to excess, cheating, or depressed. I know its sad and makes men seem one-dimensional but this is what testosterone does. Of course, in using the above list, I assume you have a good man who is caring, supportive, helpful, and attentive to your needs too.
