Sex Drive

Sex drive, or libido, is an aspect of sexuality referring to the experience of sexual urges or desires, often in anticipation of sexual gratification or sexual reproduction. An experience of sex drive may include the experience of physical arousal.

Sex drive is a separate concept from sexual attraction. While sexual attraction is directed at a target individual, sex drive is a general, untargeted experience.

Individuals who experience a sex drive may use the label libidoist, and those who do not may use the label non-libidoist.

History
The term "libido" was first coined by neurologist Sigmund Freud to describe the instinctual energy behind the experience of sexual urges. He later broadened his definition of the term to relate to other forms of desire, such as love, pleasure, and self preservation.
