What Drives the Human Sex Drive? Peering into the Portals of Virtual Sex
Abstract and Figures
Internet-based sexually explicit materials (iSEMs) continue to attract millions of viewers around the globe on a daily basis. The types of websites visited and the content viewed provide a window into the erotic souls of millions of people worldwide. There have been few studies of what these millions of viewers are seeking and why they are seeking iSEM. These websites cater to individuals seeking erotic entertainment for many reasons, such as: curiosity; to vicariously fulfil sexual fantasies otherwise unattainable, including novel behaviors, novel partners, and harem fantasies; to participate in a virtual form of voyeurism and exhibitionism; to facilitate arousal and sexual release; to reduce boredom; to enhance or incite foreplay between intimates; a source of sexual information; and others. This paper examines the popularity, content, and viewer demographics of three of the most popular websites featuring iSEMs, Youporn.com, RedTube.com, and Pornhub.com. Two hundred and sixty videos are analyzed based on sex acts, number and gender of the participants, geographic region of origin, theme /plot, location of the scene (outdoors, office, bedroom, et cetera), and whether or not a condom was used. The total number of views of these videos exceeds 1.7 Billion. In addition, the total number of views of free videos alone on these sites exceeds 110 Billion! Though viewers peruse these websites from diverse regions of the globe, the videos they upload and watch reveal sexual behaviors and erotic desires which are common to humanity, but also have regional distinctions. Based upon data obtained from these videos, a comparison is made with previous research conducted a decade ago, which explored the evolutionary motivations for sexual arousal. The results of this present study are statistically significant and in distinct contradiction to those found in the previous study, which have significant impacts upon contemporary perspectives of evolved sexual desire.

Postcopulatory competition between males, in the form of sperm competition, is a widespread phenomenon in many animal species. The extent to which sperm competition has been an important selective pressure during human evolution remains controversial, however. The authors review critically the evidence that human males and females have psychological, behavioral, and physiological adaptations that evolved in response to selection pressures associated with sperm competition. The authors consider, using evidence from contemporary societies, whether sperm competition is likely to have been a significant adaptive problem for ancestral humans and examine the evidence suggesting that human males have physiological and psychological mechanisms that allow for “prudent” sperm allocation in response to variations in the risk of sperm competition.
Most forms of pornography are produced to sexually arouse men, and Malamuth [J. Commun. 46 (1996) 8.] has argued that they do this by appealing to male interests and preferences that evolved to solve adaptive problems associated with mating in ancestral environments. If sperm competition has been an important selection pressure during human evolution, then sexual arousal may be an adaptive response to its occurrence since frequent copulation can be an effective method of paternity assurance. Consequently, although men should generally find mate sharing to be aversive, they may nevertheless find cues of increased sperm competition risk to be sexually arousing. Therefore, they should be more aroused by pornography that incorporates cues of sperm competition, than by comparable material in which such cues are absent. This prediction was tested using several indirect methods. Content analyses of pornographic images on World Wide Web sites and of commercial “adult” video releases revealed that depictions of sexual activity involving a female and multiple males are more prevalent those involving a male and multiple females. Moreover, an on-line questionnaire on self-reported preferences and an on-line preference study that unobtrusively examined image selection behavior both yielded results suggesting that the patterns observed in the content analyses do reflect male preferences and interests.
