“…Relationship duration is linked to higher intimate relationship quality and satisfaction (Amato et al, 2007), more frequent general and sexual interactions (Grøntvedt et al, 2020), quality of sex communication (Yoo et al, 2014), sexual autonomy (Uysal et al, 2012), sexual satisfaction (Fallis et al, 2016), less consistent condom use (Agnew et al, 2017), and lower levels of coercive or exchange sex (Manning et al, 2018). Although relationship length is not synonymous with relationship well-being, and breakups often help young people move away from unhealthy and/or unwanted relationships (O’Sullivan et al, 2019), healthy relationships can only endure if the individuals involved have sufficient skills to maintain them given that all relationships, even good ones, require work (Madsen & Collins, 2011). Beyond the factors capturing accrued relationship experience (number of past relationships, more time spent in past relationships), Manlove’s conceptualization of three primary relationship dimensions of young people captured our choice of current relationship attributes and behavior: relationship structure (relationship status, total number of status changes), quality (frequency of couple interactions, relationship quality, sexual satisfaction, communication, and sexual autonomy), and exchanges, including conflict (frequency of sex, consistency of condom use, substance use, sexual coercion or exchange).…”
