Sexual desire is, according to encyclopedic definition, libido. And Libido, in a more romantic and eloquent sense, is of a free-type of sensation or drive, such as a sort of psychic energy within an individual, in order to enhance personal developments.

If these natural drives, possessed within individuals, are, in any way, affected by deterring elements of a variety of matters, such could lead to causes of low libido. In a defined and realistic focus, libido, amid most popular and modern regards, is identified as an individual's driving urge to become interactive in a sexual manner. To bring conclusion to these varied, though somewhat, similar theories and views, if libido is affected by a great number of possible and probable matters, the causes of low libido will be evident in individuals' respective sexual performance levels.
