Body Image in Dyadic and Solitary Sexual Desire: The Role of Encoding Style and Distracting Thoughts

Historically, the reasons people have sex have been assumed to be few in number and simple in nature-to reproduce, to experience pleasure, or to relieve sexual tension. Several theoretical perspectives suggest that motives for engaging in sexual intercourse may be larger in number and psychologically complex in nature. Study 1 used a nomination procedure that identified 237 expressed reasons for having sex, ranging from the mundane (e.g., "I wanted to experience physical pleasure") to the spiritual (e.g., "I wanted to get closer to God"), from altruistic (e.g., "I wanted the person to feel good about himself/herself") to vengeful (e.g., "I wanted to get back at my partner for having cheated on me"). Study 2 asked participants (N = 1,549) to evaluate the degree to which each of the 237 reasons had led them to have sexual intercourse. Factor analyses yielded four large factors and 13 subfactors, producing a hierarchical taxonomy. The Physical reasons subfactors included Stress Reduction, Pleasure, Physical Desirability, and Experience Seeking. The Goal Attainment subfactors included Resources, Social Status, Revenge, and Utilitarian. The Emotional subfactors included Love and Commitment and Expression. The three Insecurity subfactors included Self-Esteem Boost, Duty/Pressure, and Mate Guarding. Significant gender differences supported several previously advanced theories. Individual differences in expressed reasons for having sex were coherently linked with personality traits and with individual differences in sexual strategies. Discussion focused on the complexity of sexual motivation and directions for future research.

The authors argue that human desire involves conscious cognition that has strong affective connotation and is potentially involved in the determination of appetitive behavior rather than being epiphenomenal to it. Intrusive thoughts about appetitive targets are triggered automatically by external or physiological cues and by cognitive associates. When intrusions elicit significant pleasure or relief, cognitive elaboration usually ensues. Elaboration competes with concurrent cognitive tasks through retrieval of target-related information and its retention in working memory. Sensory images are especially important products of intrusion and elaboration because they simulate the sensory and emotional qualities of target acquisition. Desire images are momentarily rewarding but amplify awareness of somatic and emotional deficits. Effects of desires on behavior are moderated by competing incentives, target availability, and skills. The theory provides a coherent account of existing data and suggests new directions for research and treatment.

The purpose of this investigation was to develop a self-administered questionnaire to measure sexual desire. In the development phase, items were generated and pilot-tested with 24 subjects. Based on these data, items were deleted, added, or modified. Next, in Study One, the Sexual Desire Inventory (SDI) was administered to 197 females and 117 males. Factor analyses revealed that the SDI was multifactorial; however, none of the generated factor solutions up to five factors yielded a good fit. Interpretation of the factors led to revisions of the SDI. It was hypothesized that sexual desire might consist of two related dimensions; dyadic sexual desire and solitary sexual desire. Items on the SDI were modified to measure these two dimensions, and the revised SDI was administered to 249 females and 131 males. Factor analysis supported the presence of these two dimensions. Internal consistency estimates using Cronbach's alpha revealed coefficients of .86 for dyadic sexual desire and .96 for solitary sexual desire, providing preliminary evidence for the reliability of the SDI. The implications of these findings are discussed.
