Whether in a relationship or marriage, there are some key components. If not both, one needs to take charge, engage in conversation, open and honest communication, don't get mad if one says something that you don't agree with. Learn to agree to disagree. Allow the person to be who they are and not make them into what you want them to be. Pay close attention to the others needs and accomodate them, after all there is nothing that you should not do. Sexually, be open, do everything and anything. Be spontaneous, be romantic, be sexy, be understanding and learn how to give the other their own space and not take it personal. Become a recreational companionship even if you don't like a particular sport. All these things count, keep a realtionship going. Take charge, if you feel you are getting bored, do something about it, get freaky, submit to one anothers needs, fulfill them, create themes in the bedroom, go out and have a night on the town. Be sexual, sensual, understanding, compassionate, and caring it goes a long way.
