The scenarios for sexual fantasies vary greatly between individuals and are influenced by personal desires and experiences, and can range from the mundane to the bizarre. Fantasies are frequently used to escape real-life
sexual restraints by imagining dangerous or illegal scenarios, such as
rape,
castration, or
kidnapping. They allow people to imagine themselves in roles they do not normally have, such as power, innocence and guilt. Fantasies have enormous influence over sexual behavior and can be the sole cause of an orgasm. While there are several common themes in fantasies, any object or act can be eroticized. '' by
Hokusai is an artistic depiction of a sexual fantasy. Sexual fantasies are increasingly viewed as a necessary component to a healthy relationship. Accordingly, theorists have argued that fantasies may be used to encourage and promote sexual pleasure between partners. Researchers have additionally found a positive correlation between instances of sexual fantasizing and increased
orgasm, arousal, and general contentment. The relative benefits of sexual fantasies are summarized in a statement by Stroller; "sexual fantasies are a private pornography in which we rehearse over and over again needs that are nearly impossible to fulfil in actual sex". Sexual fantasizing therefore allows an individual to fulfil desires that cannot be realistically achieved. In this sense, researchers assert that fantasizing about extra-marital, or multiple-partner sex is positively correlated with long-term partnerships. As such, sexual fantasies are viewed as means to combat sexual dissatisfaction. Sexual fantasising may also be used to settle relational hardships, as opposed to sexual dissatisfaction. For instance, women from disturbed marriages were found to fantasise significantly more often than happily married women. Creating hypothetical scenarios may be used as a coping mechanism, particularly by women, in handling stress and discomfort. As such, fantasies allow individuals to enter a new realm (e.g. experience a position of power, innocence, or guilt) that contrasts the source of anguish, and enhances feelings of self-worth. The purpose and function of sexual fantasies are explained rather differently from an evolutionary perspective. Bowlby's (1969/1982)
attachment theory asserts that the absence of adequate attachment figures can devastate self-esteem. It is suggested that more anxiously attached individuals use sex to attain emotional security. Accordingly, they might engage in sex through a longing for sexual intimacy, and increase the frequency of sexual behavior under conditions that challenge the status of their relationship. Contrastingly, the avoidant attachment type is apprehensive about the intimacy posed by sexual relations, and will take active measures to avoid feelings of closeness. Patterns of sexual behavior include emotion free sex with casual partners, engaging in sex to promote oneself, and feelings of detachment during intercourse. Sexual fantasies are likely to follow attachment-related themes. It is noted that anxious attachment individuals report significantly more instances of sexual fantasizing, and portray the self as feeble, dependable and powerless. Avoidant attachment types report fantasies in which relationships are regarded as cold, unfeeling and impersonal. As such, sexual fantasies serve the primary function of fulfilling interpersonal goals through the mode of mental representation. Evolutionary theory provides another interesting explanation as to the purpose and function of gender differences in sexual fantasies. Research literature states that women are more likely to prioritize their own physical and emotional sensations, where men conjure images of sexual partners. Women are also more likely to fantasize about a single individual with whom they have shared history, or those whom they wish to pursue a long-term relationship. Throughout the course of time, it has proved advantageous for the male to copulate with young and fertile females. They evolved an ability to decipher "fresh features" of reproductive partners; clear skin, thick hair, fuller lips, and so forth. By comparison, females are driven to reproduce on the basis of parental investment, and a quality gene pool possessed by the male. From a female perspective, the risks of copulating with multiple male partners far outweigh any potential benefits. It is therefore unsurprising that males visualize specific physical features; its origins and purpose can be found in evolution. It also follows that where males project outwardly, viewing women as a means to obtain sexual pleasure, women have become conditioned to remain passive in this role. They do so under close scrutiny of male sexual attention, to fantasize a specific and special partner. A person may have no desire to carry out a fantasy; people often use fantasies to help plan out future sexual encounters. Fantasies occur in all individuals and at any time of the day, although it has been suggested that they are more common among frequent daydreamers. Sexual fantasy is frequent during
masturbation, although this may be truer for men than for women. During sexual contact, some people can use their fantasies to "turn off" undesirable aspects of an act. Conversely, a person may use fantasy to focus and maintain arousal, such as a man receiving
fellatio ignoring a distraction. Men tend to be aware of only parts of themselves during sex—they are more likely to focus on the physical stimulation of one area, and as such, do not see themselves as a "whole". Many couples share their fantasies to feel closer and gain more intimacy and trust, or simply to become more aroused or effect a more powerful physical response. Some couples share fantasies as a form of
outercourse; this has been offered as an explanation for the rise of
BDSM during the 1980s — in order to avoid contracting
HIV, people turned to BDSM as a safe outlet for sexual fantasy. Couples may also act out their fantasies through
sexual roleplay. Fantasies may also be used as a part of
sex therapy. They can enhance insufficiently exciting sexual acts to promote higher levels of
sexual arousal and release. A 1986 study that looked at married women indicated that sexual fantasies helped them achieve arousal and
orgasm. As a part of therapy,
anorgasmic women are commonly encouraged to use fantasy and masturbation. == Common fantasies ==
