Motives between the Sheets: Understanding Obligation for Sex at Midlife and Associations with Sexual and Relationship Satisfaction.

Reasons for sex are associated with sexual and relational outcomes. This study investigated reasons for sex at last sex, with a focus on obligation (an avoidance motivation) and doing something nice for a partner (an approach motivation), and their associations with sexual and relationship satisfaction, while controlling for marital duration, age, and sexual desire. We investigated these reasons among married, midlife Canadian women ( = 324), men ( = 275), and 25 non-binary/gender queer participants 40 to 59 years of age.
