Notes: Reference groups are ever-married (Panel A) or first married at ages 22–26 (Panel B), one sex partner in last year, suburban, White, and normal weight. Models in Panel A include, but do not display, controls for age, gender, region, urbanicity, race-ethnicity, body mass index classification, physical attractiveness, attractiveness of personality, and work status. Models in Panel B include the same controls as well as the explanatory variables displayed in Panel A. N = 11,453
