Visual patterns of sexual desire. An original and exploratory study in eye-tracking

Sexual desire can be triggered by external (visual, tactile, auditory, olfactory) or internal (memories, fantasies) stimuli. However, few studies have investigated these different components of sexual desire. In our investigation, we focused on visual stimuli with the aim of establishing whether or not there exists a specific pattern of visual exploration linked to sexual desire among male and female subjects. In another words, we wanted to investigated what parts of the body visually explored are the more relevant to feel sexual desire. To assess this question, we conducted an eye-tracking study in which participants made a judgment of sexual desire, during the visualization of explicit visual stimuli. The main results for male viewers revealed that they explored the body longer than the face (P = .05). Within the body area, the chest region was scanned more extensively than the abdomen (P = .014) and the genital area (P = .003). There were no difference between the abdomen and the genital area. For female viewers, the pattern of exploration showed they explored the body longer than the face (P = .05). Inside the body area, the abdomen was scanned more extensively than the chest/pectoral region (P < .001), which in turn was scanned more extensively than the genital area (P < .001). Gender differences revealed that males fixated the genital area more frequently than females (P = .03), whereas females tended to fixate the abdomen longer and more frequently than males (P < .001), when instructed to evaluate their sexual desire.
