We're not going to tell you anything you don't already know when we say that most men like to have sex as much as possible. But it's a myth that they always want it more than women; if you're honest with yourself, you already know that, too! You know how sexy it is to feel wanted, and that feeling is only more intense in men. They need to feel wanted; their sense of masculinity demands it of them.
A common cause of unhappiness in long term relationships is that a couple's sex life dwindles as time goes on. People get busy with work, or tired, or too focused on other things, and they stop making time for it. A great sex life shouldn't just be for the honeymoon period. It should be forever.
