Sexual desire


Sexual desire is a motivational state and an interest in “sexual objects or activities, or as a wish, need, or drive to seek out sexual objects or to engage in sexual activities”. Synonyms for sexual desire are libido, sexual attraction, and lust. Sexual desire is an aspect of a person's sexuality, which varies significantly from one person to another, and also varies depending on circumstances at a particular time.

Sexual desire may be the “single most common sexual event in the lives of men and women”. Sexual desire is a subjective feeling state that can “be triggered by both internal and external cues, and that may or may not result in overt sexual behavior”. Sexual desire can be aroused through imagination and sexual fantasies, or perceiving an individual who one finds attractive. Sexual desire is also created and amplified through sexual tension, which is caused by sexual desire that has yet to be consummated.

Sexual desire can be spontaneous or responsive. Sexual desire is dynamic, can either be positive or negative, and can vary in intensity depending on the desired object/person. The sexual desire spectrum is described by Stephen B. Levine as: aversion --> disinclination --> indifference --> interest --> need --> passion.

The production and use of sexual fantasy and thought is an important part of properly functioning sexual desire. Some physical manifestations of sexual desire in humans are; licking, sucking, puckering, and touching the lips, as well as tongue protrusion.

Theorists and researchers have usually employed two different frameworks in their understanding of human sexual desire. The first is a biological framework where sexual desire comes from an innate motivational force like “an instinct, drive, need, urge, wish, or want”. Also known as sex drive. Second, a socio-cultural theory where desire is conceptualized as one factor in a much larger context (i.e. relationships nested within societies, nested within cultures). In the biological approach, sexual drive is likened to other biological drives such as hunger, where an individual will seek out food, or in the case of desire – pleasure, in order to reduce or avoid pain. Sex drive can be thought of as a biological need or craving that inspires individuals to seek out and become receptive to sexual experiences and sexual pleasure. However, members of all species (including humans) will not seek to engage in sexual activity with any conspecific, since attraction plays a large role in sexual desire. Incentive motivation theory exists under this framework. This theory states that the strength of motivation towards sexual activity depends on the strength of the stimuli (immediacy of stimuli), and if satiety is achieved, the strength of the stimuli/incentive will be increased in the future. Sex drive is strongly tied to biological factors such as “chromosomal and hormonal status, nutritional status, age, and general health”. Sexual desire is the first phase of the human sex response cycle. The traditional model for the human sexual response cycle can be represented as: Desire --> Arousal --> Orgasm --> Resolution. Sexual desire, though a part of the sexual response cycle, is believed to be distinct and separate from genital sexual arousal. It has also been argued that sexual desire is not a distinct phase in sexual response. Rather, it is something that persists through arousal and orgasm and can even persist after orgasm. Although orgasm might make it difficult for a man to maintain his erection or woman continue with vaginal lubrication, sexual desire can persist nevertheless.
