... As sexually explicit media or "pornography" has become increasingly accessible throughout developed world (Ogas & Gaddam, 2011), a burgeoning literature has emerged to test and explain what appears to be a persistent (though often relatively weak) connection between pornography consumption and the quality of committed romantic relationships (see reviews and meta-analyses in Manning, 2006;Rasmussen, 2016;Newstrom & Harris, 2016;Wright, Tokunaga, Kraus, & Klann, 2017). Though there are exceptions such as when couples view erotic material together as part of their sexual activity (Kohut, Fisher, & Campbell, 2017), the majority of studies have consistently found that more frequent pornography use tends to be negatively associated with reported relationship satisfaction as well as more specific indicators of relationship quality, especially for men (Carvalheira, Traeen, & Stulhofer, 2015;Daneback, Traeen, & Mansson, 2009;Doran & Price, 2014;Maddox, Rhoades, & Markman, 2011;Minarcik, Wetterneck, & Short, 2016;Morgan, 2011;Perry, 2016;Poulsen, Busby, & Galovan, 2013;Willoughby, Carroll, Busby, & Brown, 2016;Yucel & Gassanov, 2010). And while the majority of studies have been cross-sectional, data from longitudinal and experimental studies suggest that pornography use may indeed have a directional influence on romantic relationship quality (Gwinn, Lambert, Fincham, & Maner, 2013;Kenrick, Gutierres, & Goldberg, 1989;Lambert et al., 2012;Muussess, Kerkhof, & Finkenauer, 2015;Perry, 2017;Perry & Schliefer, 2017;Wright et al., 2017;Zillmann & Bryant, 1988), just as it may also be a consequence of poorer relationship quality (see the bi-directional effect in Muusses et al., 2015). ...
