Do most couples who report high sexual frequency also report high relationship satisfaction? Are there happy sexless couples? In this study, we take a novel approach to investigating how sexual frequency and relationship satisfaction are intertwined by using latent profile analysis to identify subgroups of couples based on how frequently the couple has sex/sexual intercourse and the relationship satisfaction of both partners. We also test how demographic (age, relationship duration, raising young children) and relational (commitment, self-disclosure, conflict) covariates are associated with profile membership. Data came from 2,101 male-female couples (82.7% of males and 95.8% of females were young adults between the ages of 20-39 years) in the German Family Panel (pairfam) study. Results revealed that couples were classified into four distinct profiles. The majority of the sample (86.38%) occupied a profile in which both partners were highly satisfied and the couple had sex frequently (just less than once a week). The second profile was characterized by low relationship satisfaction for both partners and infrequent sex (less than 2-3 times per month
3.60%). Two profiles had partners with discrepant levels of relationship satisfaction and a moderate sexual frequency (between two and three times per month and weekly): a satisfied female partner and highly dissatisfied male partner profile (4.01% of the sample) and a satisfied male partner and dissatisfied female partner profile (6.01%). The demographic covariates were rarely associated with class membership, but the relational covariate associations were robust. Couples with infrequent conflict and high levels of self-disclosure and commitment from both partners had higher odds of being in the highly satisfied and frequent sex profile compared to all other profiles.
