Perhaps one of the two always slows down at some point, or it's all about finding the right chemistry or similar needs. It's also about how the other perceives and values sex, initiation, intimacy. It's also common that when marriage comes to the picture then sex becomes something that "has to be done" for some and makes them lose interest in it. Others can become so secure in trusting in their partner that they take him for granted and when the "hunting season" is over then the passion is gone with it. Everyone is different but it's all about communicating and trying to keep what you have, instead of letting it vanish because of emotional security.

maybe this is my wife except for the "has to be done part". heaven forbid she do something for me.
