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 instabang dejting appar (Puts, 2005; Roney et al., 2006).
