You won't find many couples (besides newlyweds, perhaps, or people who have been dating less than three months, or anyone who has sex more times in a day than they eat a meal) who have perfectly synchronized sex schedules. This could be due to many factors, including fatique and illness. One way to address this is to redefine what you consider "sex." Often men fall into a trap: They define sex strictly as intercourse or oral sex. But a woman who finds herself exhausted after a long day may enjoy receiving an intimate massage as foreplay, rather than a rush to release.

Once she has relaxed, she may find herself in the mood for sex (either then or the next evening). Some couples arrange their schedule to have sex in the morning, or quickies at lunch, to get around the common problem with fatique. The stereotype is that women don't desire sex as often as men; surveys have found otherwise. But at the same time, many women are socialized to believe that they shouldn't want sex as much as men -- what makes a man a "stud" makes them a "slut." Sex can be part of your everyday life if you expand your definition to include petting, kissing, groping, teasing, massaging, masturbating and voyeurism, as well as intercourse.
