“…Indeed, theories describing differential patterns of evolutionary (SST; Buss & Schmitt, 1999) and/or cultural pressure (Eagly & Wood, 1999;Wiederman, 2005) across gender/sex lead one to not only expect levels of relationship and sexuality variables to potentially differ, but also potentially the meaning of relationship and sexuality variables. Further divergences in measurement models across gender/sex in relationship (e.g., Beam et al, 2018) and sexuality variables (e.g., Carpenter, Janssen, Graham, Vorst, & Wicherts, 2008) might be driven by differences in relational and/or sexual attention (Rubin, Peplau, & Hill, 1981), cost/benefit appraisals (see review by Haselton & Buss, 2000), experiences (Frederick, John, Garcia, & Lloyd, 2018, Horne & Johnson, 2019, goals , identity (see review by Impett & Peplau, 2006), or needs (Fisher, Moore, & Pittenger, 2012).…”
