Duration of partnership was calculated as the difference between last sex and first sex, as reported by the index participant.
Mean ± Standard Deviation. Median relationship duration was 1.2 years. Median age difference was 2 years, and the median difference in reported sex frequency was 12.
Recall interval between partners was calculated as the amount of time between index and partner participant recalling date of first sex. Date of last sex was always collected on the same interview date. Missing values for recall interval occurred when a date of first sex was missing for the partnership.
Responses captured in the joint questionnaire with the question “Thinking about one another, who do you think has more power in the relationship?”. Responses were originally expressed as “the male” vs. “the female”] and were converted, where indicated, to index vs. partner participant.
