People normally differ in the degree of sexual appetite they have. There is no single standard of sexual desire, and desire differs not only from person to person but also in the same person over one’s lifespan.

One of the most common sexual complaints among couples is a disparity in sexual desire. Sexual desire can be low for a vast variety of reasons, many of them psychological and interpersonal. But that doesn’t necessarily make it a disorder. It becomes a diagnosable condition only when it diminishes the quality of one’s life and creates distress, or a disparity arises in the sex drives of partners, evolving into a matter of unresolved contention in the relationship. Loss of sexual desire can both result from relationship problems and cause them.

Moreover, what constitutes low (or hypoactive) sexual desire is almost invariably a relative matter. Partners who use the degree of sexual desire experienced early in a relationship as a standard of comparison may label the drop in sexual desire and activity as a problem that often accompanies longer-term partnerships, when the needs of everyday living tend to prevail.
