sexual behaviour 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 behaviour 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 fantasising, 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 prioritise their own physical and emotional sensations, where men conjure images of sexual partners. Women are also more likely to fantasise 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 visualise specific physical features; its origins and purpose can be found in evolution. It also follows that where males project outwardly, viewing women and 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 fantasise 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
