“…However, it must be noted that the effect size for the sex difference in total SRS scores was small. Previous research has also found that reported sexual risk taking behaviors have been found to be higher for men than for women (e.g., Laumann, Gagnon, Michael, & Michaels, 1994;Oliver & Hyde, 1993;Poppen, 1995;Seal & Agostinelli, 1996;Vollrath, Knoch, & Cassano, 1999), although more recent studies have not found significant differences between the sexes (e.g., Browning, Kessler, Hatfield, & Choo, 1999;Fisher, 2007;Paul, McManus, & Hayes, 2000;Pedersen, Miller, Putcha-Bhagavatula, & Yang, 2002). Sex differences in sexual risk taking have been explained by a number of theories, including adherence to traditional gender roles and gender scripts (Eagly, 1987;Herek, 1986;LaPlante, McCormick, & Brannigan, 1980), personality differences (e.g., Zuckerman, 2007;Zuckerman & Kuhlman, 2000), evolutionary theory (Buss, 1998;Wilson & Daly, 1993), and even social exchange theory (Baumeister & Vohs, 2004).…”
