“…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). Researchers, however, have pointed out the statistical improbability of such large sex differences, especially in sex partners, and suggested that the effects may be due to social desirability and adherence to gender roles in reporting (Brown & Sinclair, 1999;Fisher, 2007;Maticka-Tyndale, Herold, & Mewhinney, 1998).…”
