The use of subtle strategies to have sex with an unwilling partner is harmful to a couple’s sexual well-being but these strategies remain understudied. This research examined the mediating role of communication patterns in the associations between attachment insecurities and sustained sexual coercion in 145 same- and cross-gender couples, and the moderating role of partners’ gender. In addition to actor and partner effects, results revealed significant indirect effects from attachment insecurities to sexual coercion via communication patterns, with moderating effects of gender. Results may help practitioners and researchers understand the ways attachment insecurities and dysfunctional communication patterns can manifest in the experience of subtle forms of sexual coercion within couples.
