Same sex competition usually occurs along those dimensions that are sexually preferred by the opposite sex

Women engage more in short-term sex when there is a surplus of women sex becomes cheap

Numerous studies across various cultures have provided empirical support for the assumption that sexual strategies of men and women follow the predictions of sexual selection theory. Women show a higher preference than men for mates who possess resources and are willing and interested in investing in children; men, in contrast, show a higher preference than women for physically attractive and young mates (Kenrick et al., 1994; Li et al., 2002; Brase, 2006; Roney et al., 2006; Buss and Shackelford, 2008; Conroy-Beam et al., 2015). This allows individuals that own much of the sexually preferred cues to be more choosy and do gain more easily there sexual goals. Hi attractive women were found to be particularly choosy (Buss and Shackelford, 2008) and high status men look more for younger mates than lower status men do (Grammer, 1992). Given that a high number of sexual mates is associated with fitness gains in males more than in females, women are less prone to engage in short-term sex than men are (Clark and Hatfield, 1989; Schmitt, 2005; Voracek et al., 2005; Gueguen, 2011). If women engage in short-term sex, they are particularly attracted by cues of masculinity (i.e., cues for good genes) like tallness, physical strength and deep voice pitch (Puts, 2005; Roney et al., 2006). Women are more motivated to engage in short-term sex when there is a possibility to take fitness benefits out of these good genes, i.e., when they are in the ovulatory phase of the menstrual cycle (Baker and Bellis, 1995; Pillsworth and Haselton, 2006).

In the absence of female non-verbal steering in online dating markets, we assume that a prevalence of male initiative will be more pronounced in online dating markets than in natural environments

In natural environments, the operational sex ratio (i.e., the number of males relative to the number of females in a given mating area) influences the sexual strategies of males and females. If there is a surplus of females, sexual competence between women increases and women tend to lower the preconditions for sex. In the opposite case, women’s willingness to engage in short-term sex ). The impact of the operational sex ratio in how men and women pursue their sexual strategies illustrates the interaction between evolved behavioural tendencies and environmental circumstances. We assume that this interactive mechanism will also affect mating behaviour in digital sexual contexts. Given that there is a variety of digital dating services some of them advertise rather casual sex, others advertise high quality mates and long-term commitment possibilities to http://kissbridesdate.com/sv/heta-egyptiska-kvinnor/ gain sexual goals for men and women will depend on these factors as well. However, in general we assume that the enhanced interest in many sexual mates in men will put women in digital mating markets in a more powerful position compared to men. In natural dating environments it was found that women send inconspicuously cues to men thereby controlling the first step of men’s courtship behaviour (Moore and Butler, 1989). This is also in accordance with notions of many of our students and patients: typically, men lament that their request were rarely responded while women complain about being overwhelmed by request, even without having a portrait of themselves in their account. If such a surplus of male demand is given, this will allow women to control the interaction with their male counterparts more according to their own needs. Therefore, we expect women to be more self-centred and self-oriented when communicating with men in online dating platforms. Furthermore, a surplus of male demand will also allow older women (that are less attractive to males in natural dating environments) to improve their dating chances.
