Maxim #1(a)(2): Men want to be turned on by their women. Women want to be proud of their men.
What do I mean by proud? It doesn’t necessarily mean she’s proud of your career success. It could mean something as simple and endearing as installing a mantle over her fireplace, so that when her girl friends come over for a party and ask about the fantastic looking mantle, she can tell them, with no uncertain amount of swelling pride, that her boyfriend did it. For her.
As for you women… well, men want you to look good. Period. That means:
Now you can’t do anything about your age or your genetically endowed looks, but you can do something about staying slim and keeping yourself looking as good as possible by adopting beneficial lifestyle habits and, if necessary, “getting some work done”.
If you ask me, I think women actually have it tougher keeping their partner attracted to them over the long run.
